Abstract :
In order to ensure real time running of adaptive receivers on multi-path fading channels in DS-CDMA systems, a new scheme is considered using the non-blind algorithm by jointing parallel interference cancellation (PIC) and adaptive minimum mean-squared error (MMSE) receivers, the proposed scheme has a relatively lower computational complexity compare to conventional methods. Simulations show that the symbol number of training sequences is relatively reduced and the performance of Bit Error Rate (BER) is improved too.
