Error rate performance analysis of power domain NOMA over AWGN and fading channels with generalized space shift keying in wireless 5G

Abstract

The Non-Orthogonal Multiple Access (NOMA) emerged as a latest solution to demand of high data rated with excellent reliability and robustness. In this paper, the performance analysis of the NOMA under fading channel is presented with emphasis on error rate calculations. In addition, the focus is on exploring the impact of various modulation techniques like binary phase shift keying (BPSK), Quadrature Phase Shift Keying (QPSK) and Generalized Space Shift Keying (GSSK). The simulation study has been performed on MATLAB tool and results are analyzed efficiently in the metrics of NOMA.
