做多用户检测的一些经典实用的仿真程序与大家分享了，有仿真结果，有备注易懂。-To do some of the classic multi-user detection practical simulation program to share with you, and there are simulation results, there are Notes easy to understand.

Millimeter wave (mmWave) systems will likely employ directional beamforming with large antenna arrays at both the transmitters and receivers. Acquiring channel knowledge to design these beamformers, however, is challenging due to the large antenna
