Abstract In accordance with the uplink frame structure of WCDMA system, this paper develops the LS-DRMAT algorithm proposed by Z. Rong, et al.(1997) into a new algorithm named LMS-DRMAT with training sequence. The use of training sequence does not complicate the application of the new algorithm in WCDMA system because the existed pilot bits in each WCDMA frame slot act as the the training sequence for the new algorithm. The proposed algorithm cuts down lots of computational complexity of LS-DRMAT algorithm which simplifies its application in WCDMA system. Furthermore, the simulation experiments indicate that the new algorithm can perform much lower BER than LS-DRMAT.
