通过仿真得到 信号误码率与信噪比的关 系, 从而为实际中 调制和解调 系统设计提供一定的理论依据。 同时 , 通过仿真技术的探讨 , 以期能为 专业教学改革提供一些新的思路(Received signal through the simulation bit error rate and SNR, in order to practice the design of modulation and demodulation system to provide a theoretical basis. At the same time, the adoption of simulation technology with a view to a professional teaching reform to provide some new ideas)

matlab 时频分析工具, 好用的，方便的，实用的。(matlab time-frequency analysis tool, useful, convenient and practical.)

chapter 3 of aircraft system identification

灰色预测模型，适合对指数型增长的模型进行中短期预测，如人口增长模型(Grey forecasting model of exponential growth model is suitable for short-term earthquake prediction, such as population growth in the model )

仿真FSK,ASK,PSK的simulink原代码(simulink)

这是关于数字预失真的仿真程序，应用LMS急降方法实现系数更新，对失真有很好的效果(This is the digital predistortion simulation program, the drop of the LMS coefficient update method implementation, have a good effect on the distortion)

该程序模拟仿真QPSK传输系统，对通信系统学习有帮助。(Simulation program to realize QPSK transmission system)

用MATLAB实现遗传算法的程序，可以无限制的套用，仅供参考！(it is good!)

说明：  QPSK完整的调制解调程序，直接在matlab里运行就能得出准确的结果，方便(QPSK modulation and demodulation complete program to run directly in matlab accurate results can be obtained to facilitate)

The Wavelet Neural Network This is simple example for using of modified Morlet neural network. Levenberg-Marquardt with numerical Jacobian calculation implemented. Easy to use with other optimization algorithem e.g GA,PSO, etc. The function "xox_lm" may be useful for other optimization problem easily. The function "xox_jacobian" may be useful for Jacobian calculation easily. The function "NN_fcn" may be used by the evolutionary based neural network. The activation function "modified Morlet" will be replaceable by others.
