A Useful Technique for Interference Analysis in Nakagami Fading

This paper presents a unified analytical method for computing the average E[g(x/(Sigma_k=1 ^K y_k + b))] of some arbitrary function g(.) when x is a gamma random variable and independent of the arbitrary random variables y₁, y₂, ..., y_k. This leads to new explicit expressions for the averages of some specific functions including, erfc(radicz), exp(-z), zⁿ, and In(1 + z), in terms of the moment generating functions of y₁, y₂, ..., y_K.
