The focus of this thesis is to leverage the spatial diversity gain afforded by point-to-point and collaborative multi-input multi-output (MIMO) wireless communications systems through the exploitation of space–time and space–frequency block coding. Both frequency-flat narrow band and frequency-selective broadband MIMO channels are considered. A new enhanced extended-orthogonal space–time block coding scheme is proposed for point-to-point closed-loop space–time block coding with four transmit antennas over frequency-flat MIMO channels. This method is confirmed by average bit error rate simulations to outperform both the established Alamouti scheme for two transmit antennas and a quasiorthogonal scheme for four transmit antennas. A receive antenna selection scheme is also proposed to further improve the performance of the proposed closed-loop extended orthogonal space–time scheme. [Continues.]
