摘要

随机投影码(RPC)是现代无线通信系统中实现速率自适应的一种很有前途的技术。将RPC引入到译码转发中继信道系统中,提出了一种具有速率自适应特性的分布式RPC (DRPC)方案。本文主要讨论了如何对DRPC信号进行联合解调和解码。最后,我们用一个名为goodput的评价指标来评价DRPC方案。实验结果表明,在信噪比5dB ~ 25dB范围内,DRPC方案的吞吐量比RPC方案至少提高0.4 bit/s/Hz。

Distributed random projection code scheme for decode and forward relay channel
Random projection code (RPC) is a promising technique to implement the rate adaption in modern wireless communication system. This paper introduces RPC to decode-and-forward relay channel system, and proposes a scheme of distributed RPC (DRPC) with rate adaption nature. In this paper, we discuss how to demodulate and decode signal jointly for DRPC. Finally, we evaluate DRPC schemes by an evaluation metric named goodput. Experimental results show that the throughput of DRPC schemes is higher at least 0.4 bit/s/Hz than RPC scheme at SNR ranging from 5dB to 25dB.
