摘要 在协作中继系统中应用网络编码可以提高网络的吞吐量,基于异或的网络编码并没有很好的纠错能力。提出了一种基于乘积码的网络编码方式,中继联合各个接收端的信息块,转发一次冗余块编码以提高各个接收端解码能力。理论和仿真曲线都证明了相对于简单的异或型网络编码,基于乘积码的网络编码可以提供更好的性能。 In cooperative relaying system,applying network coding can increase the throughput of the system,but it cannot provide strong error correction capability for the receivers.In this article,a new technique is proposed which combines product coding and network coding.The relay sends the redundancy of the block codes from receivers.With this structure,a better error correction capability is achieved.Both theoretical and simulation results confirm that the proposed technique can improve the bandwidth utilization.
