一种适用于TD-SCDMA系统的多用户检测算法

A Multi-user Detection Algorithm for TD-SCDMA Receiver System

利用逐次干扰抵消多用户检测结构,结合空时RAKE接收机,提出一种空时逐次干扰抵消多用户检测算法。仿真结果表明,该算法相比传统空时RAKE接收机有近5 dB的增益,误码率有了相当的改进。

Using the structure of Serial Interference Counteract （ SIC ） multi - user detection （ MUD ） and combining the space - time RAKE receiver, a new SIC MUD algorithm is proposed. The results of simulation indicate that this algorithm can improve about 5dB gain than the traditional space - time RAKE receiver and the error rate is greatly improved.
