摘要 协作多点传输(CoMP)是LTE-A实现网络无缝、高速覆盖的一个关键技术,该技术能够克服小区间干扰,提高无线频谱传输效率,可以有效解决小区间干扰的问题。依据3GPP技术报告中所确立的仿真参数标准在FTP和VoIP业务混合的场景下,对轮询和比例公平调度算法的CoMP性能和增益进行了系统级仿真并总结了仿真结果。 Coordinated Multi-point Transmission is the key to LTE-A in order to achieve high speed ＆ a seamless network. This technology is able to overcome inter-cell interferences and improve the efficiency of wireless transmission. The mixed traffic CoMP simulation platform realized according to simulation standard of tech report of3GPP is reported. Based on this simulation platform, a comparison of non-CoMP ＆ CoMP performances of round robin and proportional fairness scheduling algorithms is made.
