中文说明：基于kaiser窗的双谱线插值FFT谐波分析，这个有中文注释，看得明白，最小均方误差等算法的MSE的计算,添加噪声处理，可以动态调节运行环境的参数，包括随机梯度算法，相对梯度算法。
English Description：
Based on the Kaiser window double spectrum line interpolation FFT algorithm for harmonic analysis, the Chinese notes, to understand it, minimum mean square error algorithm MSE calculation, adding noise, can dynamically adjust the parameters of the running environment, including the stochastic gradient algorithm, the relative gradient algorithm.
