In this work, orthogonal frequency division multiplexing technique is combined with signal space diversity and error probability performance of the system is inspected for binary phase shift keying modulation over slow frequency-selective Nakagami-m and Rician fading channels. First, appropriate subcarrier coordinate interleaving techniques are obtained based on the number of subcarriers, the number of resolvable multipaths, and the fading parameters. It is shown that appropriate subcarrier coordinate interleaving techniques under some of the investigated scenarios are the same as the ones under the Rayleigh fading scenario. Subsequently, the bit error rate of the studied system is compared with the bit error rate of the original system. Further, it is demonstrated that the considered system provides significant performance gain beyond the original orthogonal frequency division multiplexing technique under different scenarios.
