Blind Multiuser Detection Based on Improved Infomax and FastICA
the capability of CDMA system is restricted by MAI and Near-far effect problems Two blind multi-user detector algorithms based on Improved-Infomax and FastICA are proposed and compared in the paper, which could detect target user effectively. These two detectors solve the order indeterminacy of ICA problem by initiating the demix vector with the target users spreading codes sequence. Simulation results show that new detectors have good performances in BER(bit error rate), convergence speed and user capability by comparing with tradihonal method.
