“…However, for the successful development of low-cost, energy efficient MCIK-OFDM D2D wireless systems, low complexity detection schemes are required. In this context, a low-complexity greedy detection method has been proposed in [7]. Unlike the ML detector, which performs an exhaustive search of all possible sub-carrier index combinations and their corresponding constellation symbols, the greedy detector (GD) first detects the active subcarriers, and then estimates their corresponding symbols.…”

Abstract-Multi-carrier index keying (MCIK) is a recently developed transmission technique that exploits the sub-carrier indices as an additional degree of freedom for data transmission. This paper investigates the performance of a low complexity detection scheme with diversity reception for MCIK with orthogonal frequency division multiplexing (OFDM). For the performance evaluation, an exact and an approximate closed form expression for the pairwise error probability (PEP) of a greedy detector (GD) with maximal ratio combining (MRC) is derived. The presented results show that the performance of the GD is significantly improved when MRC diversity is employed. The proposed hybrid scheme is found to outperform maximum likelihood (ML) detection with a substantial reduction on the associated computational complexity.Index Terms-Maximal ratio combining (MRC), multi-carrier index keying (MCIK), orthogonal frequency division multiplexing (OFDM).

“…A generalized version of MCIK is proposed in [5], where the number of active subcarriers is no longer fixed. In [6], a low-complexity greedy detector (GD) based on energy detection is proposed, and then this detector is analyzed under the generalized fading in [7].

“…However, there has been less of a focus on the development of MCIM for device-to-device (D2D) systems, where system complexity is critical. In order to address this issue, [7] proposed a low complexity energy based detection scheme for MCIM. In [8], the performance of MCIM was analyzed for in-vehicular D2D wireless networks.…”
