A Simple Basic Waveform of Chirp Spread Spectrum Communication System

Abstract

The Chirp Spread Spectrum is a widely used technology in the Internet of Things today. Frequency shift Binary Orthogonal Keying is a basic method which is used in the Chirp Spread Spectrum communication system. Its modulation waveform includes the Down-Chirp and Up-Chirp. The initial phase of the chirp signal can also be used to construct the modulation waveform. In addition to these, a new chirp based modulation waveform is reported in this paper. The parabola phase of this waveform is reshaped by utilizing the correlation detection characteristics.
