Recently, a family of transmission techniques known as Index Modulation (IM) have been proposed. IM schemes such as OFDM with index modulation (OFDM-IM) provide better performance than uncoded OFDM, especially at low SNR and in highly mobile environments. Furthermore, these schemes have found applications in modern day technologies such as large scale MIMO and Visible Light Communications (VLC). In this paper, a novel trans-receive scheme called OFDM with Generalized Index Shift Keying (OFDM-GISK) is designed and analyzed. The results show that the error performance of OFDM-GISK scheme is better than OFDM-IM, especially at high SNR's. Furthermore, the results also illustrate that the performance of OFDM-GISK falls more sharply compared to OFDM-IM at a cost of reduced spectral efficiency (SE).
