Title
Systematic design of space-frequency codes with full rate and full diversity
Abstract
In this paper, a general space-frequency block code structure is proposed that can guarantee full-rate and full-diversity transmission in MIMO-OFDM systems. The proposed method can be used to construct space-frequency codes for an arbitrary number of transmit antennas, any memoryless modulation and arbitrary power delay profiles. Moreover, assuming that the power delay profile is known at the transmitter, we devise an interleaving method to maximize the overall performance of the code. The simulation results show that under the simulated environment, the proposed SF codes outperform the existing SF codes from orthogonal designs by about 3-5 dB, and that the proposed interleaving method results in about 1-3 dB performance improvement compared to random interleaving.
