  Abstract

This paper proposes the performance enhancement scheme of a simple transmit diversity (STD) at Rayleigh fading channel with the unequal average powers on diversity branches. In the proposed STD system, the signal-to-noise ratio (SNR) of received signals on each diversity branch is estimated and then the signals, whose estimated SNR is larger than the specific SNR threshold value, are only selected for STD combining. First, the specific SNR threshold values, which give the best performance at the given SNR for the various unequal average branch power ratios, are investigated. Second, the average bit error rate (BER) of the conventional and the proposed STD system is analyzed numerically and compared in terms of the unequal average branch power ratio and the SNR. Numerical results show that the performance of the proposed STD system is better than that of the conventional as the unequal average branch power ratio increases.
