Performance Analysis Framework for NOMA Systems over Non-Identical Nakagami-m Fading Channels

Abstract

This paper proposes an analytical framework based on the H-function distribution to study the performance of non-orthogonal multiple access (NOMA)-based wireless networks. More specifically, herein we investigate the outage performance and the ergodic capacity of a three-node linear network topology where a source uses power-domain NOMA to communicate with two destinations over independent, but not necessarily identically distributed Nakagami-m fading channels. A Monte Carlo simulations campaign was carried out to support the proposed framework.
