Hardware impairments (HWI) are imperfections in hardware components that diminish wireless communication performance. Unlike Geometric-based Stochastic Models (GBSM) …
This paper proposes a cooperative uplink–downlink non orthogonal multiple access (NOMA) in an overlay cognitive radio network (CR). We examine the impact of imperfect …

In this paper, we derive the throughput of non orthogonal multiple access (NOMA) through reconfigurable intelligent surfaces (RIS) with energy harvesting. The transmitter harvests …
R Alhamad - Telecommunication Systems, 2022 - Springer
In this article, users' powers, harvesting, and sensing durations are optimized for interweave cognitive radio networks using Non-Orthogonal Multiple Access (NOMA). In the first slot, the …
In this paper, we propose the use of Intelligent Reflecting Surfaces (IRS) between the secondary source and K secondary users. The secondary source transmits the combination …
