Abstract :
Two novel concatenated space-time multiuser detectors are developed for uplink reception in DS-CDMA system with periodic spreading. They only require limited information of desired user and can be configured as blind or nonblind receiver based on the availability of pilot symbols. Simulations show that both of them have very fast convergence rate and very good steady-state performance.
