Abstract
This letter proposes spectrally efficient frequency division multiplexing (SEFDM) combined with orthogonal frequency division multiplexing (OFDM) using index modulation (IM). The conventional OFDM-IM provides energy efficiency but results in data rate (DR) loss because of inactive subcarriers. The coexistence of OFDM and SEFDM using IM (OFDM-SEM) improves the DR by avoiding frequency resource deactivation. OFDM-SEM outperforms classical OFDM-IM and SEFDM-IM in terms of bit error rate when evaluated at the same DR. The impact of intercarrier interference on OFDM-SEM and a possible solution through a pulse-shaping filter are also discussed.
期刊介绍：
IEEE Wireless Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of wireless communications. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of wireless communication systems.
