GPS信号跟踪与捕获，相关及非相关累积算法(GPS signal tracking and capture, accumulation-related and non related algorithms)

该软件实现渐变信号的瞬时频率提取，该算法采用基于小波脊的提取方法(Instaneous frequency extraction)

本代码是《通信信号处理》课程的大作业相应的代码。主要是通信信号发射端的仿真，具体功能是：1. 产生任意长度的伪随机序列，将序列映射为I,Q两路的信号，2.均方根升余弦滤波器成型. 3.经过通带衰减为3dB的倾斜滤波器（模拟信道衰落效果）4.插零，半带滤波器升抽样。 5.NCO处理单元调制(This code is communication signal processing courses corresponding to the large code. Mainly is the simulation of the communication signal transmitter, the specific functions are: 1. Produce arbitrary length of the pseudo-random sequence, the sequence mapping for the I, Q two-way signal, 2. Raise the root-mean-square filter forming 3. After passband attenuation 3dB tilt filter (analog channel fading effect) 4. Insert zero, half-band filter l sampling. 5. NCO processing unit modulation)

Matlab提高篇介绍了Matlab的语言的一些基本格式。同时提供了丰富的实例，让读者整整体会该语言。(Matlab increase of the Matlab language, the basic format. While providing a wealth of examples to enable readers to a full understanding of the language.)

用于多重回归分析的自编函数,能够画出回归曲线，列出表格。(Multiple regression analysis for self function, to draw the regression curve, listing form.)

利用matlab编程实现音乐义勇军进行曲的演奏，已保存为m-文件，可直接运行(Using matlab programming Anthem playing music, saved for the m-file, can be directly run)

本程序用于线性调频信号频率的测量，首先产生一加噪线性调频信号，再使用小波滤波去除噪声，最后使用希尔伯特变换法求信号的频率。(This procedure is used to measure the frequency of chirp signal, first generate a chirp signal with noise, and then use wavelet filtering to remove noise, and finally use the Hilbert transform method for the signal frequency.)
