  Abstract

It is considered necessary to improve the efficiency of the OFDM(Orthogonal Frequency Division Multiplexing) system, which is the current fourth generation mobile communication system, for high efficiency and high-speed communication in the future. In this paper, we design a scheme of DMIM-OFDM (Dual Mode Index Modulation Orthogonal Frequency Division Multiplexing) which is more advanced than OFDM-IM. The DMIM-OFDM system maps a symbol to all subcarriers using two types of constellation maps, which is different from a symbol mapping using an on-off keying (OOK) scheme in an OFDM-IM system. The two constellation modes do not overlap each other, and the receiver demodulates the signal by discriminating the mode of the symbol mapped to the subcarrier.
