Abstract

The exceptional multiple access technique is Non-orthogonal multiple access (NOMA) to achieve the desirable system capacity for future generation. To upgrade the spectral efficiency of cell-edge users, cooperative non-orthogonal multiple access (CNOMA) is engaged in a system, where a downlink signal is transmitted after performing superposition coding (SC). In order to observe the bit error rate (BER) performance, we get the error probability expressions. The proposed scheme can render an acceptable increase in transmission rate of a cell-edge user without demeaning the rates of near users. A sumptuous deal with current observation has been devoted to analyze the CNOMA system. Until now, the exact bit error rate (BER) expressions for proposed downlink CNOMA relaying networks have not been reported. In this article, we render the exact closed-form BER expressions for binary signaling schemes for downlink CNOMA system over additive white Gaussian noise (AWGN) channel. Lastly, the derived BER expressions are vindicated through Monte Carlo simulations. The proposed scenario increases the BER, however, it accommodates multiple users on a single carrier.
