摘　　要：近年来,多输入多输出(MIMO)技术已成为无线通信领域的一个研究热点。它可以大幅度提高通信系统的传输速率,但同时因并行传输产生了信号之间的干扰与重叠等系列问题,极大地增加了系统信号检测的复杂度。信号检测方法的的优劣直接对MIMO系统的整体性能造成影响,因此对信号检测方法的研究显得尤为重要。本文主要采用4种检测方式并进行仿真实验,结果显示在同一个MIMO信道模型中,OSIC检测的性能最优,MMSE次之,ZF最差。In recent years, multiple input multiple output (MIMO) technology has become a research hotspot in the field of wireless communication. It can greatly improve the transmission rate of the communication system, but at the same time, the parallel transmission also produces a series of problems such as interference and overlap between signals, which greatly increases the complexity of the system signal detection. The advantages and disadvantages of signal detection methods directly affect the overall performance of MIMO system. Therefore, the study of signal detection methods is particularly important.This paper mainly uses four detection methods and carries out simulation experiments. The results show that in the same MIMO channel model, the performance of OSIC detection is the best, MMSE is the worse, and the ZF is the worst.
