AM_DSB-SC_Modulation Techniques

一些关于卡尔曼滤波方面的资料，集锦类型，仅供参考(Some aspects of the information on the Kalman filter, highlights the type of reference)

根据产生的BA无标度网路模型，计算其平均度分布，以观察模型性质(Produce the BA scale network model to calculate the average clustering coefficient, the nature of the observation model)

matlab仿真，主要基于通信建模仿真等，本程序免费，欢迎下载，免费共享。(matlab simulation, simulation modeling is mainly based communications, this program free, welcome to download, free to share.)

全相位时移相位差频谱校正法的文章，帮助大家学习。(All phase shift the phase spectrum correction method, article, and help them to learn)

语音参数提取：短时过零率、短时能量、短时平均幅度、自相关序列、傅里叶分析(Speech parameters extraction: short-time zero-crossing rate, short-time energy, short-term average autocorrelation sequence, Fourier analysis)

说明：  简单的eq算法，供参考学习使用，文件为zip打包，代码较为通用可以复用(equalizer compute learn more about)

依次输入三个函数即可，若想修改全排列矩阵的大小，可在MATLAB中打开tianchongJ修改(Input function can be followed by three, if amendments to the whole matrix with the size, can be opened in MATLAB to amend tianchongJ)

本程序对OFDM这一调制方式的基本流程进行了仿真，通过高斯白噪声信道，接收信号解调，对比发送和接收信号波形，并画出功率谱密度图形(This program OFDM modulation scheme of this basic flow of the simulation carried out by white Gaussian noise channel, the received signal demodulation, compare sent and received signal waveforms and power spectral density plot graphics)

改程序包里包含中值、均值滤波、自适应中值滤波和一种改进的椒盐噪声滤波程序，前三种是给第四种作对比的，第四种方法对椒盐滤除效果很好。(Change the program package contains the value, mean filtering, adaptive median filter and an improved impulse noise filtering program is the first three compare to the fourth, the fourth method works well for removing salt and pepper.)
