A flexible space-time turbo coding scheme

Space-time coding is a promising technique for high data-rate wireless communications. We propose a flexible space-time turbo coding scheme based on the serial concatenation of turbo TCM and generalized delay diversity codes. It can achieve full diversity advantage for any number of transmit antennas with various transmission rates. Simulation results show that our codes can perform within 1.5 dB to 2 dB of outage capacity on quasi-static fading channels.
