- W4283687279 abstract "In Non-Orthogonal Multiple Access (NOMA), Bit Error Rate (BER) is a very sensitive parameter that needs to be controlled and possibly minimized. This paper adopted an inspired Cognitive Radio NOMA (CR-NOMA) technique which allocate power using a user channel condition to improve the BER. A Rayleigh fading approach and Quadrature Phase Shift Keying (QPSK) modulating and de-modulating technique are utilized. Simulation results shows that user 1 and user 2 have better BER than user 3 with user 2 having the lowest. This shows that having three users transmitting via a single channel sharing the same resources of time and frequency using inspired CR-NOMA power allocation technique, has a negative effect on the strongest user (user 3) while having a positive effect on the remaining two users. Hence, the use of inspired CR-NOMA power allocation have proven to be better than the fixed power (F-NOMA) power allocation in terms of BER, outage probability and Achievable capacity." @default.
