Abstract :
A scheme combining interference cancellation and an adaptive antenna is proposed. It can mitigate multiple access interference even if the interference signal arrives at the antenna array at the same angle as the desired signal. SIR (ratio of signal to interference) of the system is analyzed. Numerical results show a good performance improvement of such system.
