Abstract :
We propose a switched beamforming system with a multiuser detector in order to suppress the multiple access interference that is coming from the desired user´s direction. Since a multiuser detector in the proposed system work only for one beam signal, the required processing delay and the hardware complexity are significantly reduced. We have simulated the proposed system and our simulation results show that the proposed interference canceller achieves a low BER in a heavy interference channel, which conventional spatial filtering system cannot achieve
