A design of high-rate space-frequency codes for MIMO-OFDM systems

In this paper, a design of high-rate space-frequency codes (SFC) is proposed for MIMO-OFDM systems. The proposed SFC is achieved by partitioning data symbols in one OFDM block into many blocks and then precoding each block with an unitary matrix. For M/sub t/ transmit antennas, it can achieve a symbol rate M/sub t/ and it is numerically shown that it has full diversity in some interesting cases.
