We derive the MMSE channel estimator for multi-user Alamouti STBC transmissions over both flat fading and frequency selective fading channels. The derivation exploits the structure of the space-time code to reduce the complexity of the algorithm.A divide-and-conquer algorithm for channel estimation in multi-user space-time coded transmissionstext::conference output::conference proceedings::conference paper
