In this paper a novel transmission scheme that combines non-orthogonal multiple access (NOMA) and multi-carrier index keying (MCIK) is proposed. This scheme is proposed as a mechanism to enable multiple access for dense wireless device-to-device (D2D) systems that require high energy efficiency and effective interference management. The performance of the proposed scheme is analyzed in terms of the pairwise error probability (PEP) of user m. Novel closed-form expressions for the instantaneous and average pairwise error probability (PEP) over Rayleigh fading are derived. These expressions are used to investigate the detection performance of the proposed scheme over different configurations. Furthermore, a closed-form expression that approximates the overall average PEP is derived. This expression enables the performance analysis of NOMAMCIK within acceptable accuracy levels. The performance of the proposed scheme is assessed through numerical and simulation results.
