摘要：

Cooperative NOMA with simultaneous wireless information and power transfer is one possible method for enhancing the energy efficiency (EE) and spectral efficiency (SE) of fifth generation (5G) networks. Non-orthogonal multiple access (NOMA) offers superior spectrum efficiency than the traditional OMA method providing huge connectivity for machine-to-machine communication and enormous machine-type communication. In this paper, we first present a comparative study of dynamic power allocation method over fixed power allocation method to find the better schemes among them. Later, we use a dynamic power allocation scheme with cooperative communication (Cooperative NOMA) to find the performance of the far user with other transmission methods. Finally, we use the dynamic power allocation method for the far end user with SWIPT NOMA for the transmission and compare it with fixed power allocated SWIPT NOMA. © 2023 by Begell House, Inc.
