Abstract:
The 5G Mobile communication cellular networks are expanding rapidly, and with the quick development of several new
services and mobile applications are anticipated consumption of frequency and the bandwidth resources in upcoming cell phone
networks. Therefore, networks suffer from low speed and high latency. Corporative Non-orthogonal Multiple Access (C-NOMA) is
an approach method to meet the various needs of improved user fairness, high reliability, high spectral efficiency (SE), extensive
connectivity, raising data rates, high flexibility, low transmission latency, massive connectivity, low delay, higher cell-edge throughput,
and superior performance. This paper mainly focuses on power-domain (PD-NOMA), which employs successive interference
cancellation (SIC) at the receiver and superposition coding (SC) at the transmitter. Also, this paper compares C-NOMA, NOMA, and
OMA for different types of environmental fading. This paper shows how NOMA performance can be improved when combined with
numerous confirmed wireless communication network strategies, including cooperative (C-NOMA) system communications with the
help of optimization The simulation results demonstrated enhancements of cooperative (NOMA) compared to non-cooperative
(NOMA) and (OMA) with the help of MATLAB and NYUSIM simulations. The results also demonstrated the improvement is valid
with the increase of bandwidth frequency signal spectrum for the varying of near and far user distance.
