Performance Analysis of Chirp—UWB Signal Generation System

Jiming Lin

Abstract

Various Chirp-UWB signal generation systems composed of DDS and PLL are compared.Then the work principle and the performance of these generation systems are given.Also,the phase noise and the stray of the Chirp—UWB signal generation system in DDS-driven PLL are described.The dynamic simulation model with MATLAB/Simulink proves the correctness and feasibility of the system,and also provides a theoretical foundation for improving the system performance.
