摘　　要：文章研究了一种基于卷积码的协同网络编码方案,由协同通信系统结构确定对应的最优卷积码,然后通过最优卷积码确定协同中继编码。对该方案在瑞利快衰落信道条件下的误码性能进行了仿真,并与理论分集性能曲线进行比较。结果表明,由最优卷积码确定的协同网络编码方案获得了较好的性能增益。另外,由于常用最优卷积码已经确定,因此该方案容易实现。A cooperative network coding scheme based on convolutional code was researched. Optimum convolutional code, decided by the cooperative communication system structure, determines the cooperative relay coding. Bit Error Rate （BER） of this scheme was simulated under fast Rayleigh fading channels, and compared with the theoretical curve of diversity performance. Simulation results show that the studied scheme achieves much performance gain. In addition, because many optirfium convolutional codes are certain, the proposed scheme is feasible.
