摘要 在协同网络中,为了解决如何从所有候选协同节点中选择适当的协同节点进行协同通信的问题,提出了一种基于DF模式的协同节点选择策略,即根据即时信道信息来选择最优的协同节点。理论分析和仿真结果证明,该选择策略能够获得良好的性能,且候选节点在不同位置时采用路径取小准则是最优的方案。 A node selection scheme for distributive cooperative network is proposed. This scheme utilizes the instant Channel State Information （CSI） to select the optimal cooperative nodes. The theoretical and simulation results indicate that this scheme can achieve a good BER performance, and shortest path criterion is the best method when candidate nodes are dis tributed in the different area.
