现代通信系统(matlab版本)第二版，第一章的第二个例题程序.(Modern communication systems (matlab version) second edition, the first chapter of the second Example program.)

基于matlab的通断键控调制模块，跟通信原理书上的2ask调制原理类似，在调用时，需要在主函数中加入调制信号，和进制数，一般是2(Matlab on-off keying modulation of the module, with the Communication Theory book 2ask similar modulation principle, in the call, there is a need to add in the main function of modulation signal, and the hexadecimal number, typically 2)

在地震反演中需要进行流体替换的研究，流体替换中用到了gassmann方程 (Seismic inversion studies need to replace the fluid, fluid replacement used gussmannn equation)

Gabor纹理识别，使用matlab实现Gabor纹理识别(Texture recognization based on Gabor )

耳蜗实质上相当于一个滤波器组，耳蜗的滤波作用是在对数频率尺度上进行的，在1000HZ下，人耳的感知能力与频率成线性关系；而在1000HZ以上，人耳的感知能力与频率不构成线性关系，而更偏向于对数关系，这就使得人耳对低频信号比高频信号更敏感。Mel频率的提出是为了方便人耳对不同频率语音的感知特性的研究。频率与Mel频率的转换公式为(on logarithm frequency scale, under the 1000 hz, the perception of the human ear and a linear relationship with frequency In more than 1000 hz, the perception of the human ear does not constitute a linear relationship with frequency, and prefer to logarithmic relationship, which makes the human ear is sensitive to low frequency signal is better than high frequency signal. Mel frequency is put forward in order to facilitate the ear of the study of speech perception characteristics of different frequency. For frequency and Mel frequency conversion formula )

Increase the simulation time in the script, the simulated and theoretical results should converge • Use a pulse shaping filter at the transmitter • At the receiver, precede the discrete-time integrator with a multiplier by a replica of the transmitted pulse to construct a correlator

matlab的.m文件，用来测量阶跃信号仿真时的超调量，调节时间。(matlab .m file is used to measure signal simulation step when the overshoot, settling time.)

介绍了我们常用的预测方法神经网络算法的理论知识(Common prediction methods of theoretical knowledge of the neural network algorithm)
