| Abstract: | According to the noise characteristics, an integrated noise correction method based on wavelet filtering and the Principal Compoment Analysis (PCA) is proposed. The experiment data shows that the combined method is superior to a single filtering method, the former can effectively weaken the multipath effect and high frequency random noise. |
