Title: Highly accurate eta-mu approximation to the sum of M independent nonidentical Hoyt variates
Author: Santos, JCS

Abstract: Sums of Hoyt random variables occur in several wireless communication applications. Notwithstanding its practical interest, no closed-form expression exists for the sum statistics, which must be often evaluated via intricate multifold numerical integration. In this letter, we use the eta - mu distribution to approximate the distribution of the sum of M independent, nonidentically distributed Hoyt random variables having arbitrary mean powers and arbitrary fading degrees. To this end, appropriate eta - mu distribution parameters are derived. Our results show that the differences between exact and approximate statistical curves are almost imperceptible.
