数字通信中2FSK调制与解调原理及详细源代码(2FSK Digital Communication Principles of modulation and demodulation and detailed source code)

说明：  用VHDL语言编写的FFT程序，有些参考价值哦(VHDL prepared by the FFT procedure, some reference value oh)

说明：  在用混沌理论和神经网络进行短期负荷预测时，神经网络的输入的选择至关重要，该程序用matlabl实现了基于混沌时间序列的嵌入维数的选择(In chaos theory and neural networks with short-term load forecasting, neural network is essential to choose the input, the program implemented with matlabl chaotic time series based on the number of choices of embedding dimension)

基于小波变换的数字音频水印算法 水印嵌入源程序 (With the rapid growth of computers, network and multimedia technologies, powerful and low cost computers allow people to easily create and copy digital products of multimedia. The Internet has made it easy to distribute the information at very low cost. However, these technologies also can be illegally copied, modified and redistributed multimedia data without regarding for intellectual property rights ownership. )

实现信号处理的一个例子，对于学习资源的同学很有用(realize voice control,it is good for you!!)

说明：  matlab小波变换实例，用mallat快速算法将其进行频率分割，最后将低频重组，最后去噪效果(matlab wavelet transform instance, with mallat fast algorithm to the frequency division, and finally to low-frequency reorganization, the final denoising)
