Abstract :
This paper combines time-reversal space-time block coding (TR-STBC) which is for frequency-selective channel, with orthogonal frequency multiplexing (OFDM) to derive a new MIMO-OFDM system. Compared with the system which adopts STBC proposed by Alamouti, this one adopting TR-STBC exchanges the positions of OFDM modulator/demodulator and Space-time coder/decoder to reduce the computation complexity. Through simulation results, it can be seen that this scheme has better performance and can also achieve full diversity gain
