Abstract :
We propose a transmitter diversity method to be used in OFDM systems. The proposed method uses 2 transmit antennas and 4 distinct subcarriers to obtain eighth order transmit diversity gain. The proposed method utilizes both space and frequency diversity. The simulation results show that the proposed method can provide more gain than QOSTBC for DVB-H and IEEE 802.20.
