Abstract :
This paper addresses the problem of transmitting space-time interleaved coded signals over multiple-input multiple-output (MIMO) block fading channels with intersymbol interference (ISI). At the receiver, we investigate a cooperative approach in which data detection, decoding, and channel estimation are performed separately and iteratively. Computationally efficient methods based on the expectation-maximization (EM) algorithm are developed for multiple path gain estimation
