Abstract :
Parallel interference canceller (PIC) is a powerful algorithm to combat multi-user interference (MUI). In this paper, a PIC receiver for space-time block coded multiple input multiple output multi-carrier code division multiple access (STBC MIMO MC-CDMA) based on linearly constraint recursive least squares constant modulus algorithm (LCRLSCMA) is studied. Simulations indicate that the proposed algorithm has better BER performance than the traditional algorithms among different environments.
