Space-frequency turbo coded OFDM for future high data rate wideband radio systems

We propose a new bandwidth and power efficient signaling scheme for achieving high data rates over wideband radio channels exploiting bandwidth efficient OFDM modulation, multiple transmit and receive antennas and large frequency selectivity offered in typical low mobility indoor environments. Due to its maximum achievable transmit diversity gain and large coding gain, space-frequency turbo coded modulation strongly outperforms other space-frequency coding schemes recently proposed in literature. We also propose a simple way of combining space-frequency coding with OFDM delay diversity as a cost-effective method for further bandwidth efficiency increase by exploiting more than two antennas at the transmitter.
