Abstract
This paper is concerned with the novel multicarrier transmission technique, Orthogonal Frequency Division Multiplexing (OFDM) based on Index Modulation (IM), which acts as an alternative for conventional OFDM. The system generally shows improvements over conventional OFDM in achieving lower bit error rate, higher spectral efficiency, and better energy efficiency. Making it useful for various applications such as battery-powered communication devices, visible light communication, massive machine type communications, etc. Accordingly, becoming a suitable candidate for the next generation of wireless communication. In spite of its advantages over conventional OFDM, and due to their similarity, OFDM-IM suffers from the problem of high Peak to Average Power Ratio (PAPR). In this paper, a thorough review of the published works regarding PAPR reduction schemes in OFDM-IM is presented.
