dtmf 拨号程序，Pocket PC ，vc 工程演示(dialDTMF a Pocket PC (Pocket Contact) plugin to dial telephone numbers using DTMF s (aka Dual Tone Multi-Frequency) (tested under PPC2000 MIPS, PPC2000 ARM, PPC2002 ARM, Xscale WMPPC2003 and WM2003SE, WM5- if you want your processor supported either build the exe s yourself from CVS or email me and I may look into it). There is a listed of known working hardware in the FAQ.)

My matlab melp 2400 bps source code for pc

双通道语音增强算法，消除环境噪声。采用归一化自适应方法，噪噪声抵消10dB，语音保持较好可懂度。(The dual-channel speech enhancement algorithm to eliminate ambient noise. Using normalized adaptive noise noise offset by 10dB, and the voice to maintain good intelligibility.)

语音信号的矢量量化，其中vector_quantization.m为读取音频文件，转换成语音帧，求lpc及lsf参数以及进行矢量量化的主程序，a_lsf_conversion.m为主程序调用的lpc转lsf参数的子程序，INLS1.wav为音频文件。(Vector quantization of speech signals, wherein vector_quantization.m to read audio file, converted into speech frames, seeking lpc and lsf parameters and vector quantization of the main program, a_lsf_conversion.m main program calls a subroutine parameter lsf lpc turn, INLS1.wav as an audio file.)

quatization of audio signal and plot the signal after quantization

信号的hilbert变换,C＋＋代码,不用matlab的可试试(the c++ code for the hilbert transform)

这里主要是压缩感知的贪婪算法，通过OMP来实现DOA的估计，主要应用在阵列信号处理领域。(Here compressed sensing greedy algorithm OMP, the main application in the field of array signal processing to achieve the DOA estimates.)

滤波器设计 　　　产生一个连续信号，包含低频，中频，高频分量，对其进行采样，进行频谱分析，分别设计低通，带通，高通滤波器对信号进行滤波处理，观察滤波前后信号的频谱。(The filter is designed to generate a continuous signal containing the low, mid, and high frequency components, to be sampled, for spectral analysis, respectively, to design a low-pass, band-pass filter processing is performed by a high-pass filter on the signal, the spectrum of the signal of the observation before and after filtering.)

g.729编解码源代码，已经在freescale的处理器上面实现。(G.729 codec source code, has been in the Freescale processors to achieve the above.)

说明：  源程序中包含PCMu率与PCM线形之间的编解码(source contains PCMu rate between the linear PCM codec)
