We investigate a diversity scheme which employs a simple transform, symbol interleaving and decision-feedback differential detection (DF-DD) for differential phase-shift-keying signal transmission over a correlated Rayleigh fading channel. The proposed scheme merits instinct time diversity within each transmitted block and thus presents patent resistance to fading. It is shown that the proposed diversity scheme employing DF-DD significantly outperforms the previously reported diversity scheme employing two-symbol differential detection.
