摘　　要：无线通信系统中,空城分集技术能够扩大信道容量,但在实际应用中由于受移动终端物理条件的制约而难于实现。由空城分集引中出的协作分集,通过在移动终端间组成一个虚拟多天线系统,从而使空城分集得以具体实现。在介绍协作分集的概念和通信过程的基础上,着重描述了协作分集技术中的协作协议,并提出了一些该技术中仍需解决的问题。In nowaday wireless communications, spatial diversity can greatly extend the channel capacity. But with the physical limitation of the mobile terminal, it is hardly realized. Cooperative diversity, which comes from spatial diversity, can easily achieve the intention of spatial diversity by connecting the other mobile terminals to form a virtual multiple antenna arrays. In this paper, the conception and the communication process of cooperative diversity are first introduced. Then we describe several coorperation protocols, make a conclusion and put out some problems which need to be resolved.
