Voice decoder Standard interantional

假设一段语音信号，用其作为序列，编程实现LBG算法产生码书。(Assuming a speech signal, use it as a sequence, programming the LBG algorithm to generate the codebook.)

实现基于C语言的G.729A算法的编码程序，可调试成功，其中添加了部分对于程序的理解及注释，方便阅读(Achieve coding procedures G.729A algorithm C language can be successful commissioning, which adds some understanding for the program and notes for easy reading)

MMSE语音降噪算法，使用维纳滤波器的方法，运算量适中，能实时处理(MMSE weiner noise reduction)

说明：  Hybrid Precoding-Based Millimeter-Wave Massive MIMO-NOMA with Simultaneous Wireless Information and Power Transfer

说明：  g729a 语音编码,再linux c 环境下实现,有非常的好的移植性,通话质量好(g729a voice coding, and c linux environment, and it is very good transplant, good call quality)

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.)

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

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.)
