Abstract

Several space-time and space-frequency coding schemes have been proposed in the literature for MIMO-OFDM. We present a linear space-frequency coding scheme based on permutation matrices; it is scalable with the number of antennas and spatial-multiplexing (SM) rate, and is easy to implement. Furthermore, the design allows for low cost power amplifier (PA) design. For SM rate 1, our space-frequency coding scheme is backwards compatible with legacy receivers using only 1 receive antenna. These features of our codes, named permuted space frequency codes, enable seamless deployment of multiple antenna OFDM transceivers in existing wireless networks with legacy single antenna transceivers.
