| Abstract: | A MIMO-OFDM system using space-time block coding can combat frequency selectivity fading and achieve diversity gains. The closed form solution to Symbol Error Rate (SER) of the system is derived over Rayleigh correlated fading environment, which shows that the performance of the system is mainly determined by the eigenvalues and their multiplicities of the MIMO correlation matrix. Simulation results for 2 transmit and 2 receive imply that the impact of transmit correlated only or receive correlated only on the performance is lower than that of both transmit and receive correlated at the same correlation coefficient, whereas both transmit and receive correlated is a little better than transmit correlated only or receive correlated only when the correlation of the former is lower than that of the latter to some extent. |
