中文说明：ZF预编码性能和MMSE性能的仿真，意在比较二者在相同信噪比下的不同的性能。研究者们已经找到了许多预编码的算法，我想选取其中几种不同的预编码算法进行仿真，通过基站天线数的显著增加，更直观的感受到大规模阵列天线的优点，这是其一。另外，之所以现在大规模阵列天线是主要的研究方向，是因为现在用户不断增加、无线数据业务庞大，如果应用好预编码算法，可以使得单位时间内成功传送数据的数量（吞吐量）尽可能的多，也能更深度地利用空间无线资源。为能设计出更优的通信系统设计提供数据参考，使大规模天线阵列成为日后高能效绿色宽带无线通信系统的重要技术。
English Description：
Performance and simulation of MMSE performance of ZF precoding, intended to compare the different performances of the same Snr. Researchers have found a number of precoding algorithms, I want to choose several different precoding algorithms for simulation through significantly increased the number of base station antennas, more intuitive feel to a large array of benefits, which is one of the. In addition, the reason for massive arrays of antennas is now the main research direction, because now users continues to grow and wireless data service, huge, precoding algorithms if the application can be made per unit of time the number of successfully transmitted data (throughput) as much as possible, but also wireless resources in more depth in the use of space. Design can design a better communication system providing data reference, the large antenna arrays become energy efficient green future broadband wireless communications systems technical.
