An Improved LSCM Algorithm for Blind Multiuser Detection in AWGN CDMA Channels

摘要：

In this letter, we combine the LSCMA(Least Square Constant Modulus Algorithm) with the subspace approach and present a LSCM_SUB blind adaptive multiuser detection in AWGN CDMA channels. The poor performance of LSCMA in the low SNR will be improved by the LSCM_SUB algorithm. The performance of the proposed LSCM_SUB algorithm is compared with that of LSCMA. Simulation results show that the LSCM_SUB algorithm is superior to the LSCMA especially in the low SNR.
