摘　　要：为了解决用户节点无法安装多个天线的问题,提出了多节点协作通信技术来形成虚拟的多天线阵列。多节点协作是一种新的空间分集方法,不同节点彼此共享天线并相互转发信息来得到分集增益。通过研究多节点协作通信的关键技术,分析多节点协作的性能增益,指明了多节点协作的发展与应用方向。To solve the problem that some user nodes can not set multi-antenna, a multi-node cooperative communications technology is proposed to form multi-antenna array. Multi-node cooperation is a new spa- tial diversity and it achieves the diversity gain by sharing their antennas and relaying information. The key technologies of cooperative communications are studied and performance gain of cooperative diversity is analyzed. And the development direction and application prospects of multi-node cooperation are pointed out.
