多用户检测联合RAKE接收机的性能仿真

Performance Simulation of Multiuser Detection Combined with RAKE Receiver

阐述了多用户检测以及RAKE接收机的原理,提出将盲多用户检测和RAKE接收技术相结合,仿真分析了盲多用户检测联合RAKE接收机的性能,结果表明:将两项技术相结合,不仅可以克服CDMA系统固有的多址干扰,而且可以克服多径衰落,提高系统性能.

The paper describes the principle of muhiuser detection and RAKE receiver, and the algorithm of blind muhiuser detection combined with RAKE receiver is proposed. The result from simulation indicates that this algorithm is superior to single algorithm in containing multiaccess interference and muhipath fading.
