Resource Allocation for Secure Multi-UAV Communication Systems with Multi-Eavesdropper
Ruide Li, Zhiqiang Wei, Lei Yang +3
In this paper, we study the resource allocation and trajectory design for secure unmanned aerial vehicle (UAV)-enabled communication systems, where multiple multi-purpose UAV base…
On the Performance Gain of NOMA over OMA in Uplink Communication Systems
Zhiqiang Wei, Lei Yang, Derrick Wing Kwan Ng +2
In this paper, we investigate and reveal the ergodic sum-rate gain (ESG) of non-orthogonal multiple access (NOMA) over orthogonal multiple access (OMA) in uplink cellular communica…
On the Performance Gain of NOMA over OMA in Uplink Single-cell Systems
Zhiqiang Wei, Lei Yang, Derrick Wing Kwan Ng +1
In this paper, we investigate the performance gain of non-orthogonal multiple access (NOMA) over orthogonal multiple access (OMA) in uplink single-cell systems. In both single-ante…
Enhanced Quasi-Maximum Likelihood Decoding of Short LDPC Codes based on Saturation
Peng Kang, Yixuan Xie, Lei Yang +3
In this paper, we propose an enhanced quasi-maximum likelihood (EQML) decoder for LDPC codes with short block lengths. After the failure of the conventional belief propagation (BP)…
Joint Trajectory and Resource Allocation Design for UAV Communication Systems
Ruide Li, Zhiqiang Wei, Lei Yang +4
In this paper, we investigate resource allocation design for unmanned aerial vehicle (UAV)-enabled communication systems, where a UAV is dispatched to provide communications to mul…
Reliability-Based Windowed Decoding for Spatially-Coupled LDPC Codes
Peng Kang, Yixuan Xie, Lei Yang +1
In this letter, we propose a reliability-based windowed decoding scheme for spatially-coupled (SC) low-density parity-check (LDPC) codes. To mitigate the error propagation along th…
