CRC code for CCIT 16 CRC

说明：  MT4编程参考，详细介绍MQ4语言的语法和使用方法，非常实用，在网上很难找到。(MT4 programming reference, detailing MQ4 language syntax and use, very practical, it is difficult to find online.)

基于麦克风阵列用盖尔圆法进行信源数目估计。输入数据位麦克风采集的信号，阵元数目为10.(Based on microphone array，the number of sources is estimated by Gerschgrid method. Input data is obtained by microphone array and the number of array elements is 10.)

TXT信号的获取：一般都是拿到一个.WAV的信号，用cooledit或者其他的打开，另存为txt格式，注意的是，此时txt文件的前面两行会写入一些采样率的信息，将这几行删掉，程序就可以顺利得读取你保存的txt了。(TXT signal acquisition: generally get a .WAV signal, with coolit or other open, save as txt format, note that at this time txt file in front of two lines will write some sampling rate information, will These lines deleted, the program can be smooth to read your saved txt.)

富迪FM2018语音净燥及消侧音的专用IC开发资料,pdf格式,找了好久才找到的东西,(Fudi FM2018 voice net dry and antisidetone dedicated IC development information, pdf, looking for a long time to find something,)

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.)

说明：  这是一个从音频信号里提取特征参量的程序，从事此方面的同志，不妨参考(This a signal from the audio extract features parametric procedures, engaged in this regard, the comrades might reference! !)

A率13折线的编译码实现 1、了解PCM及13折线A率编码及译码的原理； 2、随机给出一个语音信号，并用A率13折线PCM对其编码； 3、将编码后的信号经过加性高斯白噪声信道，并在接收端对其进行译码； 4、分别画出原始语音信号、PCM编码信号以及译码后信号的波形。 (A rate of 13 polyline encoding and decoding implementation 1, to understand the principles of PCM and the broken line 13 A rate of encoding and decoding Two were given a voice signal, and PCM encode A rate of 13 polylines 3, the encoded signal through an additive white Gaussian noise channel, and the receiver decodes 4, respectively, to draw the waveform of the original speech signal, the PCM encoded signal and decoding signals.)

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.)
