In this article, we propose a cooperative nonorthogonal multiple access (NOMA)-enabled
simultaneous wireless information and power transfer (SWIPT) Internet of Things (IoT) …

Energy harvesting with cognitive radio and nonorthogonal multiple access (NOMA)
techniques offer a promising solution to enhance the spectral and energy efficiency in …

Cognitive radio and non-orthogonal multiple access are promising to improve the spectrum
