Time-space multi-user detection algorithm using time-varying technology for CDMA system uplink channel is proposed and the design and analysis of CDMA system with array antenna are given. Based on the DCMA coding and their spatial information, a combined array format (WLS) multi-user detection algorithm, the formula of interference plus noise ratio (SINR) and bit error rate (BER) is deduced.The simulation results show that WLS multiuser detector is effective.The CDMA system with array antenna is better than the current CDMA system Have higher system capacity and better performance.
