蜂窝系统和协作通信的结合将在抗衰落抗阴影、保障切换、扩展服务区覆盖和MIMO技术实用化方面具有极大价值。结合联合发送算法,对TD-SCDMA下行链路应用协作通信技术进行了研究并设计了实用方案,同时对该系统计算量和抗干扰能力在理论和不同的仿真条件下进行了分析,仿真结果显示了该系统具有优越的性能和良好应用前景。
Combining with cellular systems, cooperative communication (CC) will have great value in reducing multipath fading and shadow effect or enhancing system's coverage. Based on joint transmission (JT) algorithm, this paper researches the application of cooperative communication in TD-SCDMA downlink and designs a simple cooperative communication scheme. Then through simulation and analysis, the paper demonstrates that the superiority and application prosperity of this scheme.
