Abstract

According to the periodic modulation characteristics of UWB signal, its spectrum is discrete. Theoretically, only at a specific frequency point, the spectrum amplitude is non-zero. Using this feature, under the condition of equivalent sampling, according to different sampling rates, the appropriate spectrum amplitude is selected in the spectrum of the sampled signal to remove the noise and interference components, and then the time-domain signal is interpolated and low-pass filtered through the inverse Fourier transform to return the original signal and improve the signal to interference ratio of the signal.
