The achievement of our previously proposed space-time coding algorithm entitled full-rate linear-receiver space-time block code (FRLR STBC) has motivated us to propose, in this paper, a new class of high-rate space-time-frequency block codes (STFBCs) over frequency-selective Rayleigh fading channels. We have called these codes FRLR STFBCs with interleaving (FRLR STFBCs-I). FRLR STFBCs-I could achieve a full-diversity property over quasi-static channels. Simulation results also verify that the proposed schemes exhibit proper performances in comparison with the recently proposed STFBCs. The most outstanding characteristic of the newly introduced high-rate codes is the linear complexity of the maximum likelihood (ML) receiver which makes possible a fast and economical decoding process.
