在现代通信系统中，电话语音的频带被限制在300 Hz～4 kHz的范围内，带来了语音可懂度和自然度的降低。为了在不增加额外成本的前提下提高语音的可懂度和自然度，进行了电话语音频带扩展的研究。提出了一种改进的基于码本映射的语音带宽扩展算法：在码本映射的过程中，使用加权系数来得到映射码本。客观测试结果表明，用此算法得到的宽带语音的谱失真度比用一般的码本映射降低至少2%。主观测试结果表明，用此算法得到的宽带语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.

暂时只支持jpeg2000支持的 cdf97 和spline53 可以这样来测试： x=imread( E:\study\jpeg2000\images\lena.tif ) ％ see the decomposition coEfficients y=wavelift(x, 1, spl53 ) using spline 5/3 wavelet figure subplot(1,2,1) imshow(x) subplot(1,2,2) imshow(mat2gray(y)) ％ see the reconstruction precision yy=wavelift(x, 5) using cdf 9/7 wavelet ix=wavelift(yy,-5) inverse sum(sum((double(x)-ix).^2))

Electromagnetic scattering from the trees above a tilted rough ground plane generated by the stochastic Lidenmayer system is studied by Monte Carlo simulations in this paper.The scattering coEfficients are calculated in three methods:coherent addition approximation,tree-independent scattering,and independent scattering.
