摘要：

In this paper, power adaptation for a transmit antenna diversity system is considered in Rayleigh fading channels. The optimal space-time domain power adaptation that minimizes the average bit error rate is analytically derived subject to a poundxed average power constraint. Our results show that the proposed space-time domain power adaptation scheme has a signipoundcant performance gain over the conventional power adaptation in the space domain only.
