Abstract盲多用户检测算法广泛应用于码分多址(Code-Division Multiple-Access,CDMA)系统中,能够有效克服多址干扰(Multiple Access Interference,MAI)与“远-近”效应(Near-Far effect)的影响,是CDMA技术中的研究热点。对基于卡尔曼(Kalman)滤波算法的盲多用户检测器进行了研究,在白高斯噪声信道与平坦瑞利衰落信道环境下仿真分析了多址干扰与“远-近”效应对系统性能的影响。仿真实验表明,基于Kalman滤波的盲多用户检测器在两种信道中误码率性能均优于基于最小均方(Least Mean Squares,LMS)算法和递推最小二乘(Recursive Least Squares,RLS)算法的盲多用户检测器,可以有效抵抗多址干扰与“远-近”效应的影响,对提高CDMA系统容量具有十分重要的应用价值。
