自己毕设做的基于三角载波的有源电力滤波器（APF）仿真，可供（apf和pwm整流器设计参考使用）(Do your own complete set of triangular carrier-based Active Power Filter (APF) emulation available (apf and pwm rectifier design reference))

lms算法对信号进行线性预测，程序非常棒，欢迎借鉴(lms algorithm for linear prediction signal, the program is great, welcome to learn)

可以打开图片的界面，并能完成图片的梯度计算和显示(open picture)

BPSK载频估计，用它的平方谱和四次方谱进行估计，能够在0dB情况下完成有效估计(BPSK carrier frequency estimation, with its squared spectrum and quartic spectrum estimation can be completed in the 0dB case valid estimation)

说明：  关于降采样和升采样的代码展示，可以在MATLAB中运行调试，能够给出结果(The code display of down sampling and up sampling can be run and debugged in MATLAB)

测试样本集对每个模式进行加噪处理，噪声值为±0.1。若网络能对加噪模式进行正确分类，则认为该网络已训练完成。(Test sample set for each pattern plus noise processing, the noise value of ± 0.1. If the network can add noise to the model correctly classified, then that the network has completed the training.)
