Adaptive antenna array system combining the adaptive beamformer with the interference canceller for wideband DS/CDMA

We propose a scheme that combines the adaptive beamformer (ABF) and the interference canceller (IC) for wideband DS/CDMA. The high pass filter (HPF) and the IC of the proposed scheme consist of the ABF to lessen the computation time of the system. This proposed scheme is analyzed in wideband vector channels of a microcell environment. The proposed scheme provides a better cancellation of the multiple access interference than the Wiener MRC method in an adaptive antenna array system. The simulated results show that the proposed scheme achieves an improvement in system capacity.
