Abstract To improve the performance of the time domain synchronous -orthogonal frequency division multiplexing (TDS-OFDM) system, an efficient space-time-frequency coding scheme is proposed. The block coding is employed in both time and frequency dimensions simultaneously and proved to be a quasi-orthogonal design. The performance improvement of TDS-OFDM system with this method is theoretically analyzed and computer simulated, showing its superior performance in the presence of both time and frequency selective environments. Comparing to the pure space-time or space-frequency coding scheme with straightforward implementations, the proposed implementation scheme reduces the computational load by about 70% in TDS-OFDM system.
