Abstract: “Diversity and data rate over multipath fading channels in wireless communication systems can be significantly enhanced by the combined use of orthogonal space-time block coding (OSTBC) multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) techniques. However, to obtain the maximum benefits of the above schemes, the required antenna spacing at both the transmit and receive sideswill result in high-cost antenna deployments. Hence, the use of triple-polarized antennas appears to be a cost- and space-efficient alternative. In this paper, we model the triple-polarized MIMO channel and evaluate the error performance of OSTBC-MIMO-OFDM system using proposed channel model. Simulation result shows error performance improvement when using triple-polarized antennas in OSTBC-MIMO-OFDM systems compared to that of using spatially-separated uni-polarized antennas.”
