In this Letter, the channel capacity under different transmission policies is analysed using a mixture gamma distribution. Specifically, the capacity of the channel with inversion and fixed rate, optimum power and rate adaptation, and truncated inversion and fixed rate IS derived in unified exact simple closed‐form expressions. The composite α − λ − η − μ /gamma fading channel which includes most of the well‐known fading distributions as special cases, has been employed in this work. Moreover, a comparison between numerical and simulation results has been carried out to verify the validation of the derived expressions.
