Abstract
The analysis of outage performance in a Non-Orthogonal Multiple Access (NOMA) based network is conducted for a hybrid model that combines an IRS with a decode-forward relay. The use of an IRS-assisted relay network is particularly significant in environments with deep fading. The outage performance of each user in different ordered NOMA configurations has been evaluated, taking into account different numbers of IRS elements. The optimal number of users that can be accommodated by a source using NOMA for a specific threshold has been identified. The required number of active reflecting elements has been estimated to achieve a target SINR for a given order of NOMA. Additionally, a closed-form expression and its asymptotic expressions have also been derived for the outage probability of all users. The analytical results have been validated via Monte Carlo simulations.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
