最近一种基于中继信道模型的空间分集技术——协同通信技术,成为一个新的研究热点。其原理是各用户通过分布式传输和处理,分享彼此的天线和其它资源从而形成一个虚拟的多天线系统。它主要应用于蜂窝通信网络、传感器网络、无线ad-hoc网络等。本文论述了协同通信技术在无线传感器网络中几种主要的实现方法。 A recent space diversity technology based on relay channel model - cooperative communication technology, has become a new research hotspot. The principle is that each user through the distributed transmission and processing, sharing each other’s antennas and other resources to form a virtual multi-antenna system. It is mainly used in cellular communication networks, sensor networks, wireless ad-hoc networks. This article discusses several major implementations of collaborative communication technology in wireless sensor networks.
