在現(xiàn)代通信系統(tǒng)中，電話語音的頻帶被限制在300 Hz～4 kHz的范圍內(nèi)，帶來了語音可懂度和自然度的降低。為了在不增加額外成本的前提下提高語音的可懂度和自然度，進行了電話語音頻帶擴展的研究。提出了一種改進的基于碼本映射的語音帶寬擴展算法：在碼本映射的過程中，使用加權系數(shù)來得到映射碼本。客觀測試結果表明，用此算法得到的寬帶語音的譜失真度比用一般的碼本映射降低至少2%。主觀測試結果表明，用此算法得到的寬帶語音具有更好的可懂度和自然度。 Abstract: In modern communication systems， the bandwidth of telephone speech is limited from 300Hz to 4 kHz， which reduces the intelligibility and naturalness of speech. Telephone speech bandwidth extension is researched to get wideband speech and to improve its intelligibility and naturalness， without increasing extra costs. This paper put forward an improved algorithm of speech bandwidth extension based on codebook mapping. In the process of codebook mapping， weighted COEFFICIENTS were used to get mapping codebook. Objective tests show that spectral distortion of wideband speech obtained by this algorithm reduces at least 2%， comparing to conditional codebook mapping. Subjective tests show that the wideband speech obtained by this algorithm has better intelligibility and naturalness.

Abstract: The reality of modern, small form-factor ceramic capacitors is a good reminder to always readthe data sheet. This tutorial explains how ceramic capacitor type designations, such as X7R and Y5V,imply nothing about voltage COEFFICIENTS. Engineers must check the data to know, really know, how aspecific capacitor will perform under voltage.

Included are the files wav1.m, wav2.m, wavecoef.mat and readme. wav2 function implements the tree structured wavelet transform of the input matrix, up to the given level of decomposition. Wav2 uses another function called wav1, which takes the well known wavelet transform of the given matrix. Daubechies wavelet COEFFICIENTS are used for wavelet transform operation wahich is saved in wavcoeff.mat.
