g729 decoder in vocoder

利用小波分解与重构,实现图像压缩,可灵活选用其他小波,简单易懂,特别适合小波初学者.(using wavelet decomposition and reconstruction, image compression, the flexibility to choose other wavelet is simple to understand and Wavelet particularly suitable for beginners.)

this is a good story book which produce good output result on matlab

说明：  基于chebyshev的水声信号分析算法，包括多种分析结果(Chebyshev acoustic-based signal analysis algorithms, including a variety of analytical results)

A numerically-controlled oscillator (NCO) is a digital signal generator which creates a synchronous (i.e. clocked), discrete-time, discrete-valued representation of a waveform, usually sinusoidal.

短时傅立叶变换，确定时变信号其局部区域正弦波的频率与相位(short-time Fourier transform)

关于matlab描述连续信号与离散信号的相关程序及信号图形。(Description Matlab program of continuous signal and discrete signal and signal graphics.)

复旦大学matlab课程，Fourier transforms的代码以及教学课件(Fudan University matlab course, Fourier transforms of the code, and courseware)

Crash course in Matlab

频幕上的图形捕捉代码，例如在频幕上捕捉手型等，捕捉完后再进行样条插值即可相似图形(Frequency of the graphics on the screen capture code, For example, in the the frequency screen capture hand type, after their capture spline interpolation of similar figures)
