联合模拟网络编码和信道编码的迭代设计
Iterative design for the joint analog network and channel coding
摘要
Abstract
A new relay scheme based on analog network coding and joint iterative detection & decoding method is proposed for the multiple-access full-duplex relay system to further improve the bit error rate and frame error rate. The information packets from different users are superimposed after interleaving and modulation at the relay node, and then transmitted to the destination node. At the destination, the joint iterative detection and decoding approach is utilized to obtain source information. A higher coding gain can be obtained by fully exploiting information redundancy from analog network coding. Simulation results show that the proposed scheme can achieve about 5 dB improvement on the SNR compared with iterative decoding scheme based on code superposition in the case of the ideal channel condition between source and relay node.关键词
