  Abstract

In this paper, we propose a STF(Space-Time-Frequency) coded OFDM(Orthogonal Frequency Division Multiplexing) transmission scheme as an attractive solution for high bit rate data transmission in a multipath fading environment. The STF-OFDM transmission scheme that we propose in this paper is a simple transmission scheme for achieving frequency diversity gain with low complexity. Using precoding in frequency domain, we obtain frequency diversity gain and improve the SER performance of conventional ST-OFDM. The precoding scheme proposed in this paper is a very simple method that can be encoded and decoded with low complexity.
