Average of arbitrary powers of Gaussian Q-function over η–μ and κ–μ fading channels

The average of integer powers of the Gaussian Q-function over fading distributions is commonly found in the evaluation of the average error performance of wireless communication systems over fading channels. Expressions known in the literature for η-μ and κ-μ fading channels only include solutions for the average of one Gaussian Q-function and the product of two Gaussian Q-functions. This limitation has been overcome by providing a general solution for the average of arbitrary powers of the Gaussian Q-function over η-μ and κ-μ fading channels.
