  In this letter, we consider a communication scenario, where the transmitter
adopts different power adaption methods according to the instantaneous channel
state to enhance the ergodic capacity (EC) over Fisher-Snedecor F fading
channels. We derive closed-form expressions for the EC under different power
adaption methods, as well as the corresponding asymptotic EC formulas to get
some insights in the high signal-to-noise ratio region. In the numerical
results section, we compare the performance of different adaptive power
transmission strategies, and demonstrate the accuracy of our derived
expressions.
