Constellation-Based Index Modulation: A Permutational Approach,re (Q-) components of OFDM signals. Then, we propose the scheme of generalized (G-)MM-OFDM-IM, which allows a different subcarrier to utilize a signal constellation of a different size while conveying the same number of index bits. Finally, two transmit diversity schemes are designed for MM-OFDM-IM(-IQ).

Constellation-Based Index Modulation: A Combinatorial Approach,a combinatorial approach. First, we briefly review OFDM with index modulation (OFDM-IM) that is the pioneering constellation-based index modulation scheme. Then, we propose the idea of information guided precoding for OFDM to improve the spectral efficiency (SE) of OFDM-IM systems, whose principle i

Constellation-Based Index Modulation: A Permutational Approach,pproach. First, we propose the multiple-mode OFDM with index modulation (MM-OFDM-IM) scheme and extend the principle to the in-phase (I-) and quadrature (Q-) components of OFDM signals. Then, we propose the scheme of generalized (G-)MM-OFDM-IM, which allows a different subcarrier to utilize a signal

Code-Based Index Modulation,ed OFDM spread spectrum (IM-OFDM-SS), which utilizes the indices of spreading codes to convey information in addition to conventional constellation symbols. We first present the system model of IM-OFDM-SS, including the transmitter and receiver structures. Then, the bit error rate (BER) performance
