Outage Analysis of an IRS-assisted Relaying NOMA Network
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:
Transactions of Electrical Engineering is to foster the growth of scientific research in all branches of electrical engineering and its related grounds and to provide a medium by means of which the fruits of these researches may be brought to the attentionof the world’s scientific communities.
The journal has the focus on the frontier topics in the theoretical, mathematical, numerical, experimental and scientific developments in electrical engineering as well
as applications of established techniques to new domains in various electical engineering disciplines such as:
Bio electric, Bio mechanics, Bio instrument, Microwaves, Wave Propagation, Communication Theory, Channel Estimation, radar & sonar system, Signal Processing, image processing, Artificial Neural Networks, Data Mining and Machine Learning, Fuzzy Logic and Systems, Fuzzy Control, Optimal & Robust ControlNavigation & Estimation Theory, Power Electronics & Drives, Power Generation & Management The editors will welcome papers from all professors and researchers from universities, research centers,
organizations, companies and industries from all over the world in the hope that this will advance the scientific standards of the journal and provide a channel of communication between Iranian Scholars and their colleague in other parts of the world.
