In this letter, we investigate the performance of non-orthogonal multiple\naccess (NOMA), under the assumption of generalized Gaussian noise (GGN), over\nRayleigh fading channels. Specifically, we consider a NOMA system with L\nusers, each of which is equipped with a single antenna, and derive an exact\nexpression for the pairwise error probability (PEP). The derived PEP expression\nis subsequently utilized to derive a union bound on the bit error rate (BER)\nand to quantify the diversity orders realized by NOMA users in the presence of\nadditive white (AW) GGN. Capitalizing on the derived PEP expression and the\nunion bound, the error rate performance of NOMA users is further evaluated for\ndifferent special cases of AWGGN. The derived analytical results, corroborated\nby simulation results, show that the shaping parameter of the GGN (\α)\nhas negligible effect on the diversity gains of NOMA users, particularly for\nlarge \α values. Accordingly, as in the case of additive white Gaussian\nnoise (AWGN), the maximum achievable diversity order is determined by the\nuser's order.\n
