Nakagami-m衰落信道下协作中继网络编码中断性能分析

Outage performance of cooperative relay network coding in Nakagami-m fading channels

理论分析传统中继编码、伽罗华域网络编码、复数域网络编码3种编码方式中,Nakagami-m衰落信道特性、源节点与中继节点间不同功率分配和中继节点在源节点与目的节点间所处的不同位置等情形对不同编码方式中断性能的影响。计算机模拟仿真结果表明,复数域网络编码能够改善网络编码的中断性能。

This paper analyzes the outrage performance of the traditional coding, Galois field network coding, and complex field network coding based on the factors including Nakagami-m fading channel characteristics, the different power alloca- tion scheme between source and relay, and the relay position between the source and destination nodes. Computer simula- tion results show that the complex field network coding can improve the outage performance for the network coding.
