摘要：
Plenty of work have been done on Space-Time processing in which multiple transmit/receive antennas are used in conjunction with coding to exploit both spatial diversity and time diversity. Constant Mode Algorithm (CMA) is an efficient blind adaptive Multi-User Detection (MUD) algorithm for CDMA systems. In this paper, we put forward a novel receiver, which combines CMA blind adaptive Multi-user Detection with STBC technique, and compare the performances of the system using different CM algorithms including SDCMA (Steepest-Descent CMA), Standard Linearity Confine CMA(SLCCMA) and Least Squares CMA(LSCMA). Simulations have been done with multi-path Rayleigh channel.
