Abstract :
This paper focuses on the problem of turbo equalization for MIMO frequency selective fading channels under the presence of unknown co-channel interference (UCCI). We develop an approach where paths´ gains computation, UCCI plus noise covariance matrix estimation, signals equalization and detection, and channel decoding are performed in an iterative fashion. A computationally efficient method based on a MMSE criterion and successive interference cancellation (SIC) is used for channel equalization. The proposed receiver is validated through Monte-Carlo simulations
