摘要

啁啾扩频是当今物联网中广泛使用的技术。频移二进制正交键控是啁啾扩频通信系统中常用的一种基本方法。其调制波形包括下啁啾和上啁啾。啁啾信号的初始相位也可以用来构造调制波形。此外，本文还报道了一种新的基于啁啾的调制波形。利用相关检测特性重塑该波形的抛物线相位。

A Simple Basic Waveform of Chirp Spread Spectrum Communication System

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.
