- W2378889161 abstract "An improved algorithm for speech enhancement based on DCT(Discrete Cosine Transform) is presented. In the condition of low SNR, the traditional speech enhancement algorithm based on DCT has good effects. The SNR can be improved effectively. In the condition of high SNR, some useful signal components may be filtered out using the traditional algorithms. Using the new algorithm, the statistical probability that the finest DCT coefficients belong to speech signal is computed first . Then according to the adaptive thresholding values, whether these coefficients are reserved in computer median absolute deviation of the finest DCT coefficients or not is determined. The simulating results show the superiority of the proposed method over a recently reported enhancement algorithm based on DCT." @default.
