谱减法实例，已经做过实验，可以运行，只要载入数据即可(Spectral subtraction instance, has done the experiment, you can run, as long as the data can be loaded)

四旋翼小型无人直升机的建模与仿真。对直升机建立模型，进行物理分析，列出微分方程并线性化，得到传递函数和状态空间方程。(Modeling and simulation of small unmanned four-rotor helicopter. Helicopter model, physical analysis, and differential equations listed linearization to obtain the transfer function and state space equation.)

About correlation. In signal processing, cross-correlation is a measure of similarity of two waveforms as a function of a time-lag applied to one of them. This is also known as a sliding dot product or inner-product. It is commonly used to search a long duration signal for a shorter, known feature. It also has applications in pattern recognition, single particle analysis, electron tomographic averaging, cryptanalysis, and neurophysiology.

说明：  gsm的物理层仿真实现，仿真的目的不仅仅在于检查DSP程序实现的错误与否，还通过MATLAB制作相应的码表(gsm realize the physical layer simulation, the purpose of simulation is not merely to check the DSP program realize the error or not, through the production of the corresponding MATLAB code table)
