Mohamed Rihan, Maha Elsabrouty, Muta Osamu, Hiroshi Furukawa, Iterative Interference Alignment in Macrocell-Femtocell Networks, A Cognitive Radio Approach, International Symposium on Wireless Communication Systems (ISWCS2014), 2014.08, [URL], The deployment of femtocells in current and future communication systems promises an effective solution for limited indoor coverage problem and a possible gateway for mobile data offloading. In this paper, we cast a cognitive interference alignment approach suitable for heterogeneous cellular networks with a mixed macrocell and femtocell deployment. Specifically, in our approach a restricted waterfilling (RWF) algorithm is used to maximize the downlink data rate, while reserving some eigenmodes for giving the femtocell basestations the opportunity to do their transmissions even at high signal-to-noise power ratio (SNR) for the macrocell basestation. Additionally, both the cross-tier and co-tier interference is to be aligned at each femtocell user’s receiver using an Iterative Reweighted Least Squares(IRLS) algorithm. The simulation results show that the proposed interference alignment (IA) approach provides an improved sum rate for the femtocell users, compared to the conventional IA techniques, like, the leakage minimization approach and the nuclear norm based rank constraint rank minimization approach..
119. Mohamed Rihan Emam Elmeligy, Maha Elsabrouty, Muta Osamu, Hiroshi Furukawa, A Study on Downlink Interference Mitigation Based on Interference Alignment for Coexisting MIMO Femtocell and Macrocell Networks affected by Heterogeneous Pathloss and Shadowing, 電子情報通信学会 無線通信システム研究会, 2014.08, [URL], This paper considers downlink interference mitigation for two-tier cellular systems using Interference Alignment (IA). In order to manage both the co-tier and cross-tier interference in MIMO femtocell and macrocell networks, we have proposed modeling such networks as an overlay cognitive radio network in which the macrocell tier plays the role of primary user and the femtocell tier acts as the secondary user/users. The proposed framework is composed of cooperation between the two tiers by using the Restricted Water-Filling (RWF) algorithm where the PU can release some of its weakest eigenmodes to be used by the SUs. Such cooperation helps the MBS to offload some of its load to be served by the associated FBSs, meanwhile, the FBSs are now able to increase their downlink sum rates through aligning both the co-tier and cross tier interference at its users' receivers. In this paper, we extend the proposed framework to cases affected by heterogeneous path loss and shadowing. The simulation results prove the superiority of our proposed interference mitigation framework compared to the legacy interference alignment approaches in various environments..
120. Mohamed Rihan Emam Elmeligy, Maha Elsabrouty, Muta Osamu, Hiroshi Furukawa, A Study on Interference Mitigation Framework Based on Interference Alignment for Femtocell-Macrocell Two Tier Cellular Systems, 電子情報通信学会 無線通信システム研究会, 2014.07, [URL], Femtocells have been considered as a promising technology to provide better indoor coverage and spatial reuse gains in the last few years. Additionally, it can be employed in mobile data offloading scenarios in order to decrease the overburden increasing traffic carried by ordinary macrocell basestations (MBSs). Unfortunately, the interference in such two tier cellular systems represent a great technical challenge that must be avoided. In this paper, we propose an interference mitigation approach that models the femtocell-macrocell two tier cellular system as a cognitive radio (CR) system, where spectrum resources of two systems are efficiently shared without affecting each other’s operation. In addition, we propose a restricted waterfilling algorithm that makes the MBS to release part of its eigenmodes to its associated femtocell basestations (FBSs) to do their transmissions even at high signal to noise power ratio regimes. The simulation results show that the proposed approach provides an improved sum rate for the femtocell users compared to the conventional interference alignment techniques, like, the leakage minimization approach and the nuclear norm based rank constraint rank minimization approach..

128. Sherief Hashima, Muta Osamu, Said Elnoubi, Masoud Alghonimey, Hossam Shalaby, Hiroshi Furukawa, Area Spectral Efficiency Performance Comparison of Downlink Fractional Frequency Reuse Schemes for MIMO Heterogeneous Networks, Electronics and Electrical Engineering (ISEEE 2014), 2014.04, [URL], In cellular networks, fractional frequency reuse (FFR) is an effective inter-cell interference mitigation technique to achieve significant coverage improvement for cell edge users. Area Spectral Efficiency (ASE) is an important and vital factor to be improved in cellular networks and is defined as the number of transmitted information bits per unit area per unit time per unit bandwidth (i.e., $bps/Hz/m^2$). In this paper, we compare ASE of different downlink FFR schemes in MIMO Heterogeneous cellular networks~( MIMO HetNets), where the base station (BS) locations are modeled using Poission Point Process (PPP). Stochastic PPP is widely used in the design and analysis of signal processing algorithms especially for communication systems. ASEs are evaluated based on coverage probability functions for Strict FFR and Soft Frequency Reuse (SFR) in MIMO HetNets for both closed and open access cases. In the same time we illustrate not only the role but also the benefits of utilizing PPP in modeling the BS locations for analytical evaluation of two main types of FFR deployments. Numerical results show that, for SFR in both open and closed access cases, it is better to use MIMO HetNets than other techniques due to large interference resulted from utilizing the whole bandwidth inside the cell. Also, in SFR case, ASE is directly proportional to the power control factor $\beta_k$. For Strict FFR MIMO HetNet open access case, SDMA with large numbers of antenna provides higher ASE at the expense of system complexity. For better ASE in MIMO HetNet system, it is recommended to use adaptive technique between strict FFR MIMO and MU-MIMO in terms of target threshold value of signal-to-interference ratio (SIR)..

ElHalawany, Maha Elsabrouty, Muta Osamu, Adel Abdelrahman, Hiroshi Furukawa, Zero-Forcing Relay Power Allocation for TDBC-Based Bidirectional Relay Networks, Electronics and Electrical Engineering (ISEEE 2014), 2014.04, [URL], Although the amplify-and-forward (AF) relaying is an effective and simple technique for cooperative communication networks, it introduces a noise enhancement problem into the system. This problem occurs when the effects of interference and the multipath fades are amplified during the transmission from the source to the relay. AF is usually used with the multiple access broadcast (MABC) protocol which is a two phases transmission (2P) analog network coding (ANC) protocol for the half-duplex (HD) communication mode. However, MABC is not designed to utilize the direct link (DL) signal no matter how strong it is. To deal with the noise enhancement problem and improve the system performance, this paper proposes a zero-forcing based relay power allocation (ZF-RPA) scheme to be used with the time division broadcast (TDBC) protocol. The ZF-RPA scheme is used to mitigate the noise enhancement by introducing adaptive ZF gains at the relay node that inverses the channels effects between sources and relay when constructing the signal to be transmitted at the third phase of the TDBC. Analytical results of the ZF-RPA scheme is compared to the traditional variable-gain (VG-RPA) scheme under the same nodes power allocation. Simulation results show that the ZF-RPA is superior for all channel qualities in terms of the outage probability compared to the traditional VG-RPA. The total system sum rate comparison reveals that the ZF-RPA scheme could outperform the VG-RPA scheme as long as the channel qualities of the relay-transceiver links are less than certain threshold..

This work considers the use of FFR in the cellular uplink where, we analyze the uplink worst case Signal to Interference power Ratio (SIR) for three main FFR schemes strict FFR, Soft FFR, and sectored FFR. A closed form expression is derived analytically for worst SIR and best inner radius. This analytical technique is utilized to configure a FFR solution for the uplink of Orthogonal Frequency Division Multiple Access (OFDMA) cellular systems. The analysis is performed using two- tiers cellular network with uniform user density and for three different cases of FFR, sectored FFR, Soft Frequency Reuse (SFR), and strict FFR, where Frequency Reuse Factor (FRF)= 3, FRF= 4. Also the effect of power control exponent on those FFR schemes is studied. The inner radius configuration depends on equalizing the worst SIR for both inner and outer edges of the cell. Numerical results show that sectored FFR without power control yields the highest SIR followed by strict FFR with FRF= 4 . Power control exponent does not affect FFR with reuse three but strongly affects SFR and FRF= 4 as its increase reduces its SIR and inner radius. Sectored FFR without power control have the highest SE, hence sectored FFR highly balances the needs of interference reduction and resource efficiency but at the expense of increased system complexity..

ElHalawany, Maha Elsabrouty, Muta Osamu, Adel Abdelrahman, Hiroshi Furukawa, Distributed Relay Beamforming for Fairness-Aware Amplify-and-Forward Relaying under Correlated Relays Noise, Wireless Telecommunications Symposium (WTS) 2014, 2014.04, [URL], In this paper, we study the design of distributed relay beamforming for interference-limited two-way relay networks (TWRNs) under correlated relay noise. This network consists of two transceivers end nodes and N parallel amplify-and-forward (AF) relay nodes where, noise at the AF relay nodes may be correlated due to common interference or propagation through multiple hops. This paper assumes a practical scenario with correlated relay noises in contrast to the majority of the related work that assumes independent relays noise. Our objective is to maximize the worst signal-to-noise power ratio (SNR) of the two end nodes under individual relay power constraints and total relay power constraint in order to improve the users fairness for the two end nodes. This relay beamforming design is a non-convex problem taking the form of max-min optimization which could be solved by decomposing it into a series of solvable sub-problems using bisection search. Semi-definite relaxation problem (SDR) is used for the reformulation of the problem. The effect of the noise correlation on the beamformer design is analyzed for two cases, i.e., the first case when a complete knowledge of the correlation structure, represented by the relay noise covariance matrix (K), is available to the relay and the second one when no knowledge is available to the relay. Simulation results show performance improvement in terms of users fairness in comparison with un-optimized AF relaying in both cases. The obtained result indicates that the knowledge of the correlation structure increases the system performance w.r.t the case where no knowledge is available..

Frequency reuse schemes are efficient interference mitigation techniques well suited to such cellular systems. This is due to its low complexity, low coordination requirements and resource allocation flexibility. In this paper, we analyze performance of different frequency reuse schemes based on worst case signal to interference power ratio (SIR) in OFDMA downlink. A closed form expression is derived analytically for the worst SIR, Spectral Efficiency (SE), and outage rate. This analytical technique is utilized to configure a Fractional Frequency Reuse (FFR) solution for the downlink of OFDMA cellular systems. The analysis is performed using two tiers network with uniform user density for different frequency reuse schemes like FFR, Soft Frequency Reuse (SFR), and sectored FFR under different Frequency Reuse Factors (FRFs). The inner radius configuration in frequency reuse schemes depends on equalizing the worst case SIR of both outer and inner edges of the cell. Numerical results show that sectored FFR yields the highest SE and low outage probability. Hence, the sectored FFR is reasonable solution for interference reduction and resource efficiency. For SFR, it is better to use power ratios between 2 and 4 as they achieve reasonable inner radii than others. The analysis clarifies that there is a trade-off aspect between capacity and coverage related to SFR and FFR, respectively..
