中文说明：多用户MIMO通信系统中各种预编码算法合速率比较。我们研究了多种经典的预编码方法，包括迫零（Zero forcing,ZF ）、 最小化均方误差（ Minimum mean-squared error, MMSE）和THP预编码。通过仿真，我们得出结论：在传统的多用户MIMO系统下， 采用各种预编码方法的和速率性能优劣排序如下：THP>MMSE>ZF 。
English Description：
Combining rate comparison of various precoding algorithms in multiuser MIMO communication system. We study several classical precoding methods, including zero forcing (ZF), minimum & nbsp; mean squared error (MMSE) and THP precoding. Through simulation, we draw a conclusion: in the traditional multi-user MIMO system, the rate and performance of various precoding methods are ranked as follows: THP & gt; MMSE & gt; ZF.
