Dual mode orthogonal frequency division multiplexing with index modulation(DM-OFDM-IM) is recently proposed, which modulates all subcarriers to eliminatethe limits of spectrum efficiency in OFDM with index modulation (OFDM-IM). InDM-OFDM-IM, the subcarriers within each subblock are divided into two groups,which are modulated by two distinguishable constellation alphabets drawn fromthe distinct two constellations.  In this paper, a new constellation design for DM-OFDM-IM is proposed based onthe pairwise error probability (PEP) analysis. In previous works, the design ofthe constellation pair is naive and induces much power. Also, a new bit mappingscheme for DM-OFDM-IM is proposed. The proposed bit mapping scheme can relievethe catastrophic effect of the index demodulation error incurring burst oferrors, which is the endemic problem of the index demodulation systems. Thesimulation results show that the proposed constellation pair and the proposedbit mapping scheme substantially enhance the BER performance of the DM-OFDM-IMthan the conventional DM-OFDM-IM.
