Performance Analysis of SWIPT Cooperative-NOMA Over Rayleigh Fading Channel.

A potential solution for the improvement of energy efficiency (EE) and spectral efficiency (SE) of the fifth generation (5G) networks is the combination of cooperative NOMA with simultaneous wireless information and power transfer (SWIPT). In order to provide support to massive connectivity for machine-to-machine communication & massive machine-type communication, non-orthogonal multiple access (NOMA) provides higher spectral efficiency than the convention OMA method. Our aim in this paper is to first examine the performance of the cooperative communication with NOMA for a far end user with the conventional OMA. Secondly, we have examined the performance of the cooperative NOMA with SWIPT when there is no direct link is present between the base station (BS) and the far end user under Rayleigh fading conditions. The performance is measured for a fixed data rate of the far user on the basis of outage probability, achievable data rate and instantaneous data rate of both near and far user.
