The α-η-κ-μ model was recently proposed as a generalized fading and can include all well-known small-scale fading models as special cases. In this letter, we investigate the channel capacity of wireless communications that operate in α-η-κ-μ fading channels. More specifically, novel and exact expressions for the channel capacity under different adaptive transmission policies are derived in terms of infinite series. Previous results can be obtained through our newly derived expressions by combining and/or specializing the various parameters of the α-η-κ-μ model. Moreover, our derived analytical expressions assess the impact of fading parameters on the channel capacity, and are illustrated by simulation results.
