A new type of interference cancellation multiuser receiver with pilot symbol aided coherent demodulation method is proposed and analyzed.According to our theoretical analysis and numerical analysis
the multiuser access interference is canceled out from the baseband received signal.This new method makes full use of the frame structure of WCDMA
without adding new pilot channel
the coherent demodulation can be obtained and it is integrated with the multiuser receiver.The theoretical analysies also prove that this method can improve the system performance greatly.The results also demonstrate that substantial capacity improvements can be obtained with successive interference canceller whose stage is 2.
