Abstract :
In this study, a novel scheme called orthogonal frequency division multiplexing with index modulation (OFDM-IM) is proposed for frequency selective channels. In this scheme, the information is conveyed not only by only M-ary signal constellations as in classical OFDM, but also by the indices of the active subcarriers, which are determined according to the information bits. Different transceiver structures have been investigated for the proposed scheme and it has been shown via computer simulations that OFDM-IM system achieves significantly better error performance than the classical OFDM.
