Method and apparatus for improving signal to noise ratio using wavelet decomposition and frequency thresholding |
摘要 |
A method and apparatus for improving the signal to noise ratio of an information carrying signal wherein a wavelet transform up to a predetermined level is computed, a frequency thresholded signal which is indicative of noise is derived from the wavelet transform, and the frequency thresholded signal is subtracted from the information carrying signal.
