Abstract

An integrated space-time equaliser is proposed for interference suppression in a DS/CDMA receiver. It outperforms the existing time-domain-only counterpart in terms of near-far resistance and capacity in multipath channels. In addition, the use of unequal reduced lengths between array elements can significantly reduce the complexity without greatly sacrificing the performance. A comparison in MSE between simulation and analytical results is also presented.
