一种协同通信中的联合检测算法研究

A Research of Combining Detection Algorithms in Cooperative Communications

对协同通信中的协同空间复用目的节点的检测算法进行了研究,提出了全局似然联合检测、局部似然联合检测和局部迫零联合检测等3种算法。仿真结果显示全局似然联合检测性能最优,局部似然联合检测和某些局部迫零联合检测也具有较好的性能。

This paper makes a research of the detection algorithms of the destication node with the cooperative spatial multi-plexing technique, and provides three detection algorithms of the cooperative spatial multiplexing： the global ML combining detection, the local ML combining detection and the local ZF combining detection algorithms. The simulation shows that the global ML combining detection algorithm has the best capability. The local ML combining detection and some kinds of the local ZF combining detection algorithms also have good capability.
