Space Time Serial Concatenated Turbo Coded Modulation

Space-Time trellis-coded modulation (ST-TCM) which combines modulation and coding in a single entity delivers exceptional performance in static enviroment such as AWGN and flat fading channels. On the other hand, bit- interleaved coded modulation (BICM) which gives up the joint decoder/demodulator architecture in favor of two separate entities outperforms ST-TCM in selective fading channels, but suffers performance loss in static channels. This paper proposes a space-time serial concatenated coding schemes which consist of two ";simple"; constituent encoders and an interleaver namely: ST serial concatenated Turbo-coded modulation (ST-SCTCM). Both theory and simulation results demonstrate that ST-SCTCM outperforms either ST-TCM or BICM across different channel conditions.
