摘要：

为了进一步改善多址接入全双工中继系统的误比特率和误帧率，提出了基于模拟网络编码和联合迭代检测与译码技术的中继通信方案．该方案中，中继节点对来自不同用户的信息经过交织和调制后进行信号叠加，发送到目的节点．目的节点采用联合迭代检测和译码方法获得源信息．该方案能够充分利用模拟网络编码提供的信息冗余，获得更好的编码增益．计算机仿真结果表明，如果源-中继节点信道理想，当误比特率为10^-5时，相比较于码字叠加迭代译码方案，所提方案有将近5dB的信噪比改善．

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 5dB 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.

Key words: signal superposition, full-duplex, analog network coding, relay, iterative methods
