  Abstract

The selection transmit diversity is known to be an effective means to mitigate the deep fading in a wireless channel. However, it may not completely eliminate the SNR fluctuation of a received signal at the receiver. This paper presents an application of an adaptive modulation effectively exploiting the SNR variation over the time for a higher spectral efficiency to the conventional selection transmit diversity and analyzes its performance. Numerical results show that the proposed scheme can achieve a SNR gain of about 7 dB over the conventional selection transmit diversity without using the adaptive modulation technique in a flat Rayleigh fading environment, when the BER of 10￣3 and the spectral efficiency of 2 bps/Hz are required.
