Abstract

This paper presents a new space-time iterative technique for equalizing multiple input multiple output (MIMO) channels with unknown co-channel interference (UCCI). The proposed method is based on a successive interference cancellation (SIC) technique derived under a minimum mean square error (MMSE) formalism. Computer simulations show that attractive performance can be achieved even with simple coding schemes
