Abstract :
This paper derives a new MIMO-OFDM system. This system adopts time-reversal space-time block coding (TR-STBC) to replace STBC proposed by Alamouti. When TR-STBC is combined with orthogonal frequency multiplexing (OFDM), the computation complexity is lower than other MIMO-OFDM schemes. Through simulation, this scheme has better performance than the one which adopts STBC proposed by Alamouti and it also can achieve full diversity gain
