Abstract
In this letter, an in-band full-duplex integrated sensing and communications (ISAC) system based on orthogonal frequency division multiplexing (OFDM) modulation is proposed. We introduce a chirp-scrambled OFDM that enables simultaneous super-resolution distance estimation and communication. A monostatic ISAC node employs a super-resolution distance estimate scheme that utilizes the chirp property of the echo signal, achieving cm-level estimation in practical band-limited communication settings. A communication node demodulates information symbols from the receive chirp-scrambled OFDM signal with no loss of communication performance compared to the conventional OFDM without chirp scrambling.
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.
