Abstract :
Two classes of parallel and serial concatenated space-time turbo codes with full rate and full antenna diversity are proposed. Two 2-dimension LOG-MAP decoding algorithms are also developed to decode the proposed codes. The simulation results as an example of parallel code demonstrate that the code outperforms other space-time turbo codes on independent fading channels. Under conditions of same bit rate, the proposed scheme brings about 7∼15dB gain at bit error rate 10-6 and frame error rate 10-3 relative to schemes proposed before over slow and fast fading channels.
