中文说明：被广泛应用的MIMO预编码技术，将所有线性预编码技术（包括迫零，最小均方误差，奇异值分解等算法加以归类，仿真比较其误比特率性能，具有很好的指导意义。
English Description：
MIMO pre coding technology has been widely applied, will all the linear pre coding technology (including zero forcing, minimum mean square error, singular value decomposition algorithm to classify, simulation comparison of the bit error rate performance, has the very good guiding significance.
