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.
