摘　　要：本文提出了MC-CDMA系统中一种预处理的盲多用户检测算法P-LSCMA,它是对MC-CDMA接收信号 进行预处理,消除部分多址干扰,然后再用LSCMA算法消除由于信道在各个子载波上对信号造成的影响,从而在每次 迭代合并中提高了系统的检测性能。A pre-processed least squares constant modulus algorithm （P-LSCMA） in MC-CDMA system is proposed in this paper. The received signal is multiplied by the spread code of expected user in frequency domain in every iteration, and then the LSCMA is applied to the pre-processed signal to cancel the influence to the signal which caused by channel on every sub-carrier.

关 键 词：多载波 CDMA 盲多用户检测 最小二乘恒模算法
