  Abstract

A new transmit antenna selection and shuffling (AS²) method for spatially correlated double space time transmit diversity (DSTTD) systems is proposed. The proposed method allows dumb antennas and the superposition of multiple signals at the same transmit antenna, whereas the conventional methods consider the antenna shuffling (AS) only. According to the simulation result, the proposed method provides a 1.8 ㏈ signal-to-noise ratio (SNR) gain over the conventional methods for spatially correlated transmit antennas. Although the number of candidates for AS² is much higher than that of AS, it is found that the number of candidates for AS² can be reduced to 36 by using the characteristics and properties of preprocessing matrices, and among them, only 6 candidates are almost always chosen. Next, we empirically compare the bit-error-rate (BER) performance of the proposed method with the conventional spatial multiplexing (SM) technique with antenna selection. Simulation results show that the proposed method outperforms the SM technique.
