摘　　要：CoMP是LTE-A的关键技术,采用CoMP技术的小区能有效避免同频干扰,提升小区边缘用户的吞吐率。通过对下行CoMP中3种技术的比对,总结出三者的特性。结合CoMP的测试,分析了下行CoMP中的算法过程及运行机制。对比优化前后效果,结合基站开启下行CoMP功能后对下载速率有提升的验证,对下行CoMP进行推广应用。CoMP is the key technology of LTE-A which can effectively avoid the same frequency interference, improves the throughput of cell edge users. Through the comparison of the three technologies in the DL CoMP, the characteristics of the three are summarized. Combined with the tests of CoMP, the algorithm process and operation mechanism of DL CoMP are analyzed. Accord the comparison of the effect of optimization and combined with the verification of improvion of the download speed of base station which open the CoMP function, DL CoMP is popularized application.
