Choice of Thresholds for Wavelet Shrinkage Estimate of the Spectrum,

Abstract

The purpose of this thresholding level is to make the reconstructed log-spectrum as nearly noise- free as possible. In addition to being pleasant from a visual point of view, the noise-free character leads to attractive theoretical properties over a wide range of smoothness assumptions. Previous proposals set much smaller thresholds and did not enjoy these properties.
