Abstract: The noise could affect the location precision in ultra wideband wireless sensor network. In order to solve this problem, a time of arrival (TOA) estimation algorithm based on envelope extraction was proposed. The noise component of signal could be effectively removed by the multiresolution analysis of wavelet transform. Then the envelope of denoising signal was extracted by Hilbert transform. Finally, the maximum value of the first envelope was used as the TOA estimation value. The simulation results showed that the algorithm could suppress the noise and improve estimation precision.

Key words: ultra wideband, noise, wavelet, Hilbert transform, envelope extraction
