An investigation of a multiple-input-multiple-output communication system with the Alamouti Space-time code

Abstract

This thesis investigates the fundamentals of Multiple-Input-Multiple-Output (MIMO) radio communication systems with space-time codes. A MIMO system was design using the Alamouti space-time code. The modulation technique was binary phase-shift keying (BPSK). Matlab with Simulink was used to simulate the design, which was tested in both an additive white Gaussian noise (AWGN) channel and in a multipath fading channel with AWGN. Theoretical performance was derived for both channels and compared to simulated results. The original receiver design was changed to incorporate a maximal-ratio combiner (MRC) receiving technique with channel state information (CSI). The theoretical performance for this design was determined and compared to simulated and published results.
