Abstract :
In this article, we propose a serial concatenated single differential space-time (SDST) coded OFDM systems, in which blind SDST coding is serially concatenated with convolutional coding. The OFDM is incorporated for maintaining satisfactory performance in both time and frequency selective fading channels at low SNR. The encoding and iterative decoding processes are thoroughly studied and the improved performance is demonstrated via simulations.
