Abstract :
Capacity of MIMO-OFDM system with exponential correlation matrix and multi-path channel was researched. Based on SVD, factors of correlation coefficient and the number of multi-path and antenna were analyzed. The Monte-Carlo simulations present that capacity of MIMO-OFDM system would decrease obviously as correlation coefficient increasing in large SNR; and it would also increased with number of multipath at power limited situation; capacity for NrtimesNt = NtimesN system is increase with N, and number the antenna in receiver has more effect on capacity when Nr is un-equal to Nt.
