Characterization and Efficient Exhaustive Search Algorithm for Elementary Trapping Sets of Irregular LDPC Codes
Yoones Hashemi, Amir H. Banihashemi
In this paper, we propose a characterization of elementary trapping sets (ETSs) for irregular low-density parity-check (LDPC) codes. These sets are known to be the main culprits in…
Massive Machine Type Communication with Data Aggregation and Resource Scheduling
Jing Guo, Salman Durrani, Xiangyun Zhou +1
To enable massive machine type communication (mMTC), data aggregation is a promising approach to reduce the congestion caused by a massive number of machine type devices (MTDs). In…
Optimal Energy Allocation For Delay-Constrained Traffic Over Fading Multiple Access Channels
Antonious M. Girgis, Amr El-Keyi, Mohammed Nafie
In this paper, we consider a multiple-access fading channel where users transmit to a single base station (BS) within a limited number of time slots. We assume that each user h…
Proactive Location-Based Scheduling of Delay-Constrained Traffic Over Fading Channels
Antonious M. Girgis, Amr El-Keyi, Mohammed Nafie +1
In this paper, proactive resource allocation based on user location for point-to-point communication over fading channels is introduced, whereby the source must transmit a packet w…
GMD-Based Hybrid Precoding For Millimeter-Wave Massive MIMO Systems
Tian Xie, Linglong Dai, Xinyu Gao +2
Hybrid precoding can significantly reduce the number of required radio frequency (RF) chains and relieve the huge energy consumption in mmWave massive MIMO systems, thus attracting…
Intracell Interference Characterization and Cluster Inference for D2D Communication
Hafiz Attaul Mustafa, Muhammad Zeeshan Shakir, Ali Riza Ekti +2
The homogeneous poisson point process (PPP) is widely used to model temporal, spatial or both topologies of base stations (BSs) and mobile terminals (MTs). However, negative spatia…
