In this paper, several new high-rate STBCs with transmit diversity gain of two are proposed. The proposed STBCs can flexibly support either three or four transmit antennas, and a code rate of between two to four. We show that they have good symbol dispersion property that leads to better BER performance under spatially-correlated MIMO channels or when the number of transmit antennas is reduced from four to three. They also have better coding gain and lower decoding complexity than some existing high-rate STBCs at the same spectral efficiency.
