OFDM:
multi carrier transmission has become an attractive technique in many wireless standards to meet the increasing demand for high data rate communication systems. One of the most popular multicarrier techniques, orthogonal frequency division multiplexing (OFDM), has developed into a widely-used scheme for wide band digital communication. The major advantage of OFDM over single-carrier schemes is its ability to cope with frequency-selective fading channel with only one-tap equalizer.
Fig: OFDM with index modulation
an OFDM with generalized index modulation (OFDM-GIM). The generalization is proposed in two aspects. First, a more flexible selection of active sub carriers is proposed to further improve the spectral efficiency.We also demonstrate that the two generalization schemes are compatible with each other and their combined scheme greatly outperforms existing works in spectral efficiency and BER performance, at the cost of a little higher complexity.
