Data Process Method Based on Multi-resolution Analysis for Spectral Signals

In this paper, we presented a data process method based on wavelet transform for spectral signal. The discrete wavelet transform are discussed. A fast wavelet algorithm for one-dimensional signals is described. Using the principle of multi-resolution analysis, we reach the aim of filtering signals, data compression and removing low-frequency disturbance. This method is tested using field measured spectral data. The result shows that this new method is very effective.
