The effective capacity of a communications system using unified models is analysed. To obtain a simple closed‐form mathematically tractable expression, two different unified approximate models have been used. The mixture gamma distribution which is a highly accurate approximation approach has been first employed to represent the signal‐to‐noise ratio of fading channel. In the second approach, the mixture of Gaussian distribution which is another unified representation approach has been utilised. A comparison between the simulated and numerical results using both distributions over composite α − η − μ /gamma fading channels have been provided.
