Abstract :
Capacity of MIMO-OFDM system with channel estimation error was researched. Based on SVD, factors about channel estimation error percent and the number of multi-path were analyzed. The Monte-Carlo simulations present that capacity of MIMO-OFDM system would decrease obviously as channel estimation error increasing in large SNR; it would loss almost half capacity when estimation error ups to 10%.
