SEP matlab code for WSNs clustering

说明：  脉冲编码调制(Pulse Code Modulation,PCM)技术编程(Pulse Code Modulation)

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.)

说明：  MeLPe Codec 1200 bps

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.)

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.)

FS1016源代码，用MATLAB语言编写得，好东西啊(FS1016 source code, using MATLAB been prepared, good things ah)

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,)

说明：  线性预测编码（LPC）是主要用于音频信号处理与语音处理中根据线性预测模型的信息用压缩形式表示数字语音信号谱包络（en:spectral envelope）的工具。它是最有效的语音分析技术之一，也是低位速下编码方法高质量语音最有用的方法之一，它能够提供非常精确的语音参数预测。(linear predictive coding)

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.)
