Large System Analysis of Cooperative Multi-cell Downlink Transmission via Regularized Channel Inversion with Imperfect CSIT
Jun Zhang, Chao-Kai Wen, Shi Jin +2
In this paper, we analyze the ergodic sum-rate of a multi-cell downlink system with base station (BS) cooperation using regularized zero-forcing (RZF) precoding. Our model assumes…
Performance of Joint Channel and Physical Network Coding Based on Alamouti STBC
Yi Fang, Lin Wang, Kai-Kit Wong +1
This work considers the protograph-coded physical network coding (PNC) based on Alamouti space-time block coding (STBC) over Nakagami-fading two-way relay channels, in which both t…
Performance Analysis of Protograph LDPC Codes for Nakagami- Fading Relay Channels
Yi Fang, Kai-Kit Wong, Lin Wang +1
In this paper, we investigate the error performance of the protograph (LDPC) codes over Nakagami- fading relay channels. We first calculate the decoding thresholds of the protog…
Message Passing Algorithm for Distributed Downlink Regularized Zero-forcing Beamforming with Cooperative Base Stations
Chao-Kai Wen, Jung-Chieh Chen, Kai-Kit Wong +1
Base station (BS) cooperation can turn unwanted interference to useful signal energy for enhancing system performance. In the cooperative downlink, zero-forcing beamforming (ZFBF)…
