各种形式的方向图，波束形成中有常规波速形成，等等(Various forms of pattern, with a conventional beamforming beamforming, etc.)

压缩文件里边包含好几个合成地震记录的程序，包括楔形模型，断层等，有的还画出了地震记录，反射系数的振幅谱~(the zip file contains several synthetic seismogram programs, including wedge model, fault model, etc., some even draw the earthquake records, the reflection coefficient of amplitude spectrum ~ )

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)
