Universal Space-Frequency Block Coding for MIMO-OFDM Systems

In this paper, we propose a universal design of rate-Mt full-diversity space-frequency (SF) block codes over MIMO frequency-selective fading channels for any number of transmit antennas. The full-diversity can be proved to be the product of the number of transmit antennas Mt, receiver antennas Mr and channel taps L. The performance of the proposed SF codes are simulated and compared with some existing SF codes. The full-diversity of the proposed rateMt SF block codes is further validated from the simulated cases
