We generalize the space time code structure of "a transmit diversity scheme for channels with intersymbol interference", "Single-carrier frequency domain equalization for spacetime block coded transmissions over frequency selective fading channels", and define new Space Time Block Codes per Block. Compared to Space Time Block Codes they are well adapted to selective frequency channels. We thus propose an efficient receiver consisting of first a space time code frequency domain detector followed by a predictive decision feedback equalizer with frequency domain feedforward filter and time domain feedback filter. Simulations show the efficiency of the whole structure.
