STAR-RIS Aided MISO SWIPT-NOMA System with Energy Buffer: Performance Analysis and Optimization
Kengyuan Xie, Guofa Cai, Jiguang He +1
In this paper, we propose a simultaneous transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) and energy buffer aided multiple-input single-output (MISO) simul…
Performance Analysis and Resource Allocation of STAR-RIS Aided Wireless-Powered NOMA System
Kengyuan Xie, Guofa Cai, Georges Kaddoum +1
This paper proposes a simultaneous transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) aided wireless-powered non-orthogonal multiple access (NOMA) system, wh…
Performance Analysis of a Two-Hop Relaying LoRa System
Wenyang Xu, Guofa Cai, Yi Fang +1
The conventional LoRa system is not able to sustain long-range communication over fading channels. To resolve the challenging issue, this paper investigates a two-hop opportunistic…
Outage-Limit-Approaching Protograph LDPC Codes for Slow-Fading Wireless Communications
Yi Fang, Pingping Chen, Guofa Cai +3
Block-fading (BF) channel, also known as slow-fading channel, is a type of simple and practical channel model that can characterize the primary feature of a number of wireless-comm…
