Abstract :
In this paper, a new scheme for space-frequency-time block coded OFDM system is presented. In the proposed scheme, we considered a combination of high order space-time code with OFDM utilizing joint diversity of space-frequency-time over frequency selective fading channels to provide high quality of transmission for broadband wireless communications. Numerical results are provided for evaluating the performance of several forms of the proposed system.
