Optimal Data Transmission on MIMO OFDM Channels

This thesis investigates the Physical Layer performance of single-input single-output (SISO) wireless communications systems, as well as multi antenna techniques such as multiple-input single-output (MISO) and multiple-input multiple-output (MIMO) systems, the last two utilizing the Alamouti-based space-time block coding (STBC) technique. All cases are based on the IEEE 802.16-2004 standard with OFDM using different values of coding rates. International Telecommunications Union (ITU) channel models are selected for the wireless channel in the simulation process. The particular setting we are interested in is the case where partial Channel State Information (CSI) is fed back to the transmitter for optimal control on the transmission rate. The performance results of the simulated SISO, MISO and MIMO systems are compared among themselves.
