On power adaptation strategies in nakagami fading channels

Research output: Chapter in Book/Report/Conference proceeding › Conference contribution › peer-review

Abstract

We consider power adaptation for constant rate transmission in Nakagami fading channels under the assumption that channel state information is provided at both the transmitter and the receiver. We derive average BER expression for channel inversion (CI) with peak and average transmission power constraints, and compare it to optimal power adaptation policy in minimizing the average BER. We find that the CI provides nearly optimal performance as the line-of-sight component and/or available average transmission power increase, and there exists an optimal peak-to-average power ratio for each channel parameters when the CI is employed.
