中继信道Chong-Motani-Garg容量界的前向解码可达性
Achievability of Chong-Motani-Garg relay channel capacity bounds using forward decoding
摘要
Abstract
To reduce decoding delay of a communication scheme which is backward.decoding-based and achievable Chong-Motani-Garg capacity bounds,a novel forward-sliding-window decoding-based communication scheme is proposed.In this scheme,if w=(w1,w2)is the message to be sent in block b,the relay will decode message w1 and generate a new message Z at the end of block b,and the receiver will decode message W1 at the end of block b+1 and decode message Z and W2 at the end of block b+2.Analysis results show that this new communication scheme can achieve the same Chong-Motani-Garg bounds and the decoding delay is only two blocks which is much shorter than that of backward decoding.Therefore,Chong-Motani-Garg bounds Can be achieved by a forward decoding-based communication scheme with short decoding delay.关键词
