Performance Analysis of a Low-Complexity Detector for MCIK-OFDM Over TWDP Fading

This letter analyzes the performance of a low-complexity detection scheme for a multi-carrier index keying (MCIK) with orthogonal frequency division multiplexing (OFDM) system over two-wave with diffuse power (TWDP) fading channels. A closed-form expression for the average pairwise error probability over TWDP fading channels is derived. This expression is used to analyze the performance of MCIK-OFDM in moderate, severe, and extreme fading conditions. The presented results provide an insight on the performance of MCIK-OFDM for wireless communication systems that operate in enclosed metallic structures, such as in-vehicular device-to-device wireless networks.
