An iterative noncoherent detection method of coded and symbol interleaved differential space-time modulation (DSTM) is proposed in flat Rayleigh fading channels. Like differential phase shift keying (DPSK), DSTM can be considered as a recursive convolutional code. A soft-output a posteriori probability (APP) decoder of DSTM is proposed in flat Rayleigh fading channels. In the decoder, multiple-symbol...
A technique intended to improve the performance of bit-interleaved coded modulations over non Gaussian channels is presented. It introduces signal space diversity by the means of modifications to the constellation mapper and to the corresponding demapper. A rotation of the constellation is followed by a signal space component interleaving. Iterative processing at the receiver side is shown to provide...
