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 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.
