Broadcast Service Technology Empowered by Integrated Communication and Navigation

Abstract

This paper provides an overview of broadcast service technology enabled by integrated communication and navigation. The communication-navigation integration technique is based on orthogonal time frequency space (OTFS) modulation technique, OTFS is a novel two-dimensional modulation technique that can be used in high Doppler spread scenarios. OTFS has novel and important features designed in the delay-Doppler domain. In the case of high Doppler spread, OTFS can provide more significant performance improvements than OFDM. In addition, the broadcast technology empowered by the integrated communication and navigation technology is then introduced. In this paper, the existing research results are reviewed and summarized to derive the advantages of communication-navigation integrated technology-empowered broadcasting service techniques.
