摘　　要：协作分集技术是一种新型的空间分集技术,它通过使多个具有单天线的终端共享彼此的天线,达到获得多天线分集增益的目的。协作分集技术能够提高系统的容量,降低系统的误码率。本文主要介绍了协作分集的概念分类,以及在多用户协作条件下的系统模型。Cooperative diversity is a new spatial diversity technology. It makes terminals with single antenna share their antennas with each other in order to get multi-antenna gain. Cooperative diversity can increase the capacity and reduce the error rate. This paper mainly introduces the conception of the cooperative diversity, and the system model in multi-user condition.
