Improving performance of coherent coded It can be shown that if the channel estimates are perfect(a1=a1, a2 OFDM systems using space time transmit a2)diversity can be achieved

OFDM Systems (N subcarriers) Frequency Available bandwidth is divided into N B subband.Each symbol△f (1kHz) occupies a narrow band but longer time Time
