Space-time domain power adaptation for transmit antenna diversity in fading channels

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

The optimal space-time domain power adaptation that minimizes the average bit error rate in a transmit antenna diversity system is analytically derived subject to a fixed average power constraint. Our results show that the proposed space-time domain power adaptation scheme has a significant performance gain over the conventional power adaptation in the space domain only.
