说明：  实现数字滤波（刚开始接触不知道分类对不对）请见谅(Digital filter (do not know the beginning of exposure classification is correct or not), please forgive me)

this file gives the parameters of a model estimated from given data. this is usfull in estimationa and forecasting

系统辨识工具箱，找了很久，亲测可用。matlab没装工具箱的可以下载(system identification toolbox)

Tamir模型的源代码,主要研究在树林信号传播时的衰减模型。(The Tamir model source code, mainly in the woods signal propagation attenuation model.)

这是一个EMD分解程序，matlab运行的环境，只要导入数据，肯定可以运行(This is an EMD decomposition process, as long as the import data, they can definitely run)

HIGH PASS FILTERING WITH USING 3X3 MASK

模拟人耳听觉系统的gammatone滤波器组(Simulate the human auditory system gammatone filter banks)

fingerprint enhancement using DCT

对qpsk一个整体的仿真，从源信号的生成，调制，加载波，解调等，步骤清晰，与通用教材原理图逐步仿真而来(Qpsk simulation of a whole, the signal generated from a source, modulation, plus carrier demodulation step clarity, and general simulation of materials gradually from the schematic)

说明：  多通道和单通道接收到的北斗信号数据，利用接收到的北斗数据（.dat .txt文件），进行解析，得到初始伪距，平滑伪距，载波相位，并计算其标准差，并画图。(The Beidou signal data received by multi-channel and single channel are analyzed by using the Beidou data (. Dat. TXT file). The initial pseudo range, smooth pseudo range and carrier phase are obtained, and the standard deviation is calculated and plotted.)
