Full-Diversity Full-Rate Optimum Transmit Signal for SFN

To improve performance of single frequency networks employing distributed transmit antennas,some transmit signals are introduced in this paper. Pair-wise error probability is derived and one transmit signal isproposed to obtain the achievable diversity order. Then, two full-diversity (maximum diversity) transmit signaldesign methods are proposed. To optimize the first proposed transmit signal, one interleaved-partition subcarriergrouping scheme, establishing a tradeoff between receivers' location and performance, is introduced. Simulationresults are presented in a representative scenario to demonstrate the performance gains offered by the proposedtransmit signals.
