The generalised maximum SINR array processor for personal communication systems in a multipath environment

Abstract

This paper presents the generalised maximum signal-to-interference-plus-noise ratio (MSINR) array processor, which is the extension of MSINR from the single to the multiple desired-signal case. The problem of optimal multiple desired signal processing is of particular importance in a multipath fading environment. Therefore, the performance of the MSINR processor is evaluated for personal communication systems (PCS) in a Rayleigh fading channel with interference. Strong interference is expected in the PCS channel, due to the overlay in the spectrum allocated to PCS. It is shown that the generalised MSINR processor outperforms other methods the minimum variance distortionless response (MVDR) and the minimum mean square error (MMSE) interference cancellers, yielding the best bit error rate (BER).
