Two major challenges of applying Alamouti's space-time block coding (STBC) to a practical system are the imperfect channel estimation and rough synchronization. Without the full knowledge of channel state information (CSI), the receiver is highly likely to make wrong decisions; on the other hand, without the time alignment of the transmit antennas, the system will suffer from the inter-symbol interference (ISI). The subject of this thesis is to propose a novel receiver to improve the overall system performance. In the first part of this thesis, we focus on the performance analysis of STBC with imperfect channel estimation and synchronization. In the next part, we investigate the L-MMSE estimator and derive its general solutions. Finally, a novel receiver based on the L-MMSE estimator and a modified parallel interference cancellation (PIC) detector is proposed.
