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 y
₁
, y
₂
, ..., y
_k
. This leads to new explicit expressions for the averages of some specific functions including, erfc(radicz), exp(-z), z
ⁿ
, and In(1 + z), in terms of the moment generating functions of y
₁
, y
₂
, ..., y
_K
