Abstract

This paper presents an improved STF (space-time-frequency) coded MIMO-OFDM (multiple-input and multiple-output, orthogonal frequency-division multiplexing) system for two transmit antennas. In this system, we devise an interleaving method which can maximize diversity gain and achieve optimal system performance with a moderate decoding complexity. Complete characterization of the proposed STF-OFDM scheme is provided and its BER (bit error rate), BLER (block error rate) and spectral efficiency performance is evaluated. Result of the simulation shows that the proposed scheme significantly improves the system performance.
