Denoising Analysis on UWB Communication in Mine Tunnels
In the EMC interference environment of mine,we found the EMC is white noise and pulse interference.The UWB signal pulses is short and signal power spectral density distributed in wide band is very low.This article mainly proposes a de-noising method of Wavelet transform modulus maxima in signal band,focused on the traditional low-pass filter that can only remove the outside-band noise.Simulation results show that the scheme can effectively retain the signal singularity based on information to achieve obvious noise reduction
