Method of Chirp-UWB Signal Generation Based on DDS and PLL

Liu Luo-kun

Abstract

Because of wide bandwidth of UWB signal,the previous method of signal generation can not be used in UWB communication system.A signal generation of Chirp-UWB based on DDS+PLL is introduced.This method combines the advantages of DDS and PLL.Modeling and simulating by ADS and Matlab prove this method can output high performance signal,and it satisfies demand of the design well.This scheme has been used in a UWB communication system well.
