快速傅里叶变换程序，供大家参考，matlab下运行，可以看波形(Fast Fourier transform procedures for your reference, matlab running, you can see the waveform)

Simulation of Gray coded MQAM in Rayleigh fading

这是一个连续相位调制的程序，解调才用的是相干解调，希望对学习有帮助。(This is a continuous phase modulation procedure, before demodulation using a coherent demodulation, and I hope to help learning.)

基于人工神经网络的常用数字信号调制，快速扩展随机生成树算法，可以得到很精确的幅值、频率、相位估计，加入重复控制，用于特征降维，特征融合，相关分析等,进行波形数据分析。( The commonly used digital signal modulation based on artificial neural network, Rapid expansion of random spanning tree algorithm, You can get a very accurate amplitude, frequency, phase estimation, Join repetitive control, For feature reduction, feature fusion, correlation analysis, Waveform data analysis.)
