MIMO SIC检测合并技术
MIMO SIC Detection Combination Technique
多天线技术（MIMO，Multi Input Multi Output）是第四代移动通信的一个重要发展方向，有利于提高系统的容量和传输速率，其发展备受关注。通过干扰消除技术有利于消除MIMO系统的多天线干扰，所以串行干扰消除技术（SIC，Successive Interference Cancellation）广泛应用于MIMO系统中。对于SIC的检测合并技术有很多种，最常用的有最大比合并（MRC，Maximum Ratio Combining）和最小均方误差合并（MMSE，Minimum Mean Square Error）。本文主要针对这两种合并方式讨论SIC的检测合并。MRC属于检测复杂度较低的一种合并方式，MMSE属于性能较好的一种。本文通过在不同调制方式下比较二者的性能和复杂度，力求得到一个折中。本文研究2*2天线配置下的MIMO SIC系统，在第二级检测比较两种合并方式的性能与复杂度，得出不同调制方式下对于检测合并方式的选择。
MIMO is an important orientation technique in the 4th mobile telecommunication. For its superiority of improve the system capacity and transmission rate, it is on high attention now. Multi-antennas interferences can be eliminated by SIC technique, so SIC technique is usual used in the MIMO system. There are many detection combination techniques in SIC, and the traditional ones are MRC and MMSE. In this paper, MRC and MMSE is studied. By compare the performance and complexity of these two techniques in different Modulation mode, we get a compromise. This paper mainly evaluates the performance and the complexity of the two techniques in the 2*2 antenna configure, and conclude the selection of the detection combination technique in different Modulation mode.
