摘　　要：本文主要叙述了一种基站阵列接收方案中的盲自适应算法。在此算法中,我们使用一般的信息位作为训练信号来实现智能天线权值的更新。本方法的贡献在于,和导频位辅助LMS—DRMTA算法一样比传统的LS—DRMTA算法大大降低了运算量,同时该算法比导频位辅助LMS—DRMTA算法获得了更好的误码率、系统容量以及更好的波束图。A new algorithm which is used in smart-antenna system is presented in this paper which is named the blind adaptive algorithm. The main contribution of the new algorithm includes three aspects. First this algorithm has less computational load than the LS-DRMTA which is the same with the pilot-associated LMS-DRMTA; second this algorithm has the better bit error rate (BER) and the better capacity of a CDMA cell/sector than the pilot-associated LMS-DRMTA; third this algorithm has a better beam picture than pilot-associated LMS-DRMTA.
