High-rate full-diversity space-time-frequency codes for MIMO multipath block-fading channels

In this paper, we propose a systematic design of rate-M/sub t/ full-diversity space-time-frequency (STF) code for MIMO frequency-selective block-fading channels. The full-diversity can be proved to be the product of number of transmit antennas M/sub t/, receiver antennas M/sub r/, fading blocks M/sub b/ and channel taps L. The performance of the proposed STF codes are simulated and compared with some existing SF codes. The full-diversity of STF is further validated from the simulated case.
