摘　　要：综合了近年来发展起来的线性类解相关多址干扰消除技术,对各种线性类解多址干扰技术的性能进行了分析,对其实现进行了一定程度的探讨,并得出了实际系统的误码率表达式。分析表明,该类算法能够较好地克服边缘效应,具有很好的应用前景。In this paper,we synthetically rese arch the new kind of decorrelating mu lti -user receiv-er.we analyze the performance and ap plication future of this receiver ,and draw the new BER expression in more practical system.Analysis results show that this kind of receiver c an partly eliminate the disadvan-tage of edge effect in traditional linear decorrelating receiver,so can be wildly used in CDMA system.
