采用傅里叶变换，频域中进行行为识别的方法，具体请参考MACH3D的那篇论文-The Fourier transform, frequency domain behavior recognition method, specific reference MACH3D of that paper

超宽带窄带抑制变换域的方法，通过自适应脉冲-Transform domain ultra-wideband Narrowband suppression methods, an adaptive pulse

DFT 是连续傅里叶变换在时域和频域上都离散的形式，将时域信号的采样变换为在离散时间傅里叶变换频域的采样。在形式上，变换两端（时域和频域上）的序列是有限长的。

采用遗传算法改进原基于神经网络的变换域通信系统接收方法，对收发两端频谱环境不一致条件下TDCS有效接收信息-The genetic algorithm is used to improve the receiving method of the transform domain communication system based on the neural network, and the TDCS can receive the information effectively under t
