中文说明:应用背景在LTE通信中,使用了MIMO-OFDM技术,虽然很好的解决了小区内用户的干扰问题,但是却带来了更为严重的小区间用户干扰问题,小区间干扰成为限制系统容量和边缘用户服务质量的重要因素,如何解决小区间干扰问题成为大家共同关注的话题。关键技术本程序仿真了采用MIMO通信的各种干扰抑制算法的性能,包括干扰抑制比合并算法(IRC)、最大比合并算法(IRC)、迫零算法(ZF)、最小均方误差算法(MMSE)等,并绘制误码率曲线图,可以方便的对比个算法的性能。
English Description:
Application backgroundMIMO-OFDM technology is used in LTE, while a good solution to the problem of interference of the users within the cell, but the more serious inter cell interference problems, inter cell interference has become an important factor to restrict the system capacity and cell edge user quality of service, how to solve the inter cell interference problem has become a topic of common concern.Key TechnologySimulation of the process of the MIMO communication, various kinds of interference suppression algorithm performance, including interference suppression ratio (IRC) by merging algorithm, maximum than merging algorithm (IRC), forced to zero (ZF) algorithm, minimum mean square error (MMSE), and the mapping of bit error rate curve, the performance of the comparison algorithm.
