系统地阐述了低密度校验码基于图模型的编译码思想，介绍了密度进化理论，对影响低密度校验码纠错性能的两个主要因素——度序列设计和围长设计进行了深入分析，详细介绍并设计了LDPC的编解码(Systematic exposition of the LDPC graph model based codecs idea, introduces the density evolution theory, the two main factors that affect the performance of LDPC error correction- the degree of sequence design and girth design depth analysis, detailed and designed LDPC codec)

用于进行声压转换的matlab文件，声压数据来源于ansys软件的计算后导出来的。(Used for sound pressure to convert matlab file, sound pressure data from the calculation software ansys guide out.)

在matlab环境下实现语音信号的预处理，包括分帧，加窗，滤波，并进行端点检测，绘图。(Voice signal preprocessing in the Matlab environment, including the frame, windowing, filtering, and endpoint detection, drawing.)

pitch 的相关程序，自己编写的，可以条用，很好的，赶快下吧(pitch of the relevant procedures, their preparation, can be used, very good, quickly, are you)

应用于低压电力线载波通信的OFDM系统仿真，采用了压缩感知的方法进行信道估计，与LS算法比较，仿真效果良好。(Used in low-voltage power line carrier communication OFDM system simulation, using the compressed sensing method for channel estimation, simulation good effect.)

SGALAB工具箱，最新beta5的，主要是刚才从pudn上下了一个垃圾工具箱，东西已经损损坏无法解压了。所以给大家传个新的，肯定能用(Toolbox SGALAB latest beta5, mainly just up and down from a garbage pudn Toolbox, things have been unable to extract a damage loss. So give us a new mass, be sure)

基于谱减法的语音增强算法，谱相减法及其变形方法总体上运算量较小，容易实时实现，增强效果也较好，是目前最常用的一种方法(Spectral subtraction based speech enhancement algorithm, spectral subtraction method and the deformation of the whole volume of the smaller operations, easy real-time implementation, and enhance the results would be better, is the most commonly used in a way)
