The paper decomposes the original adaptive filter into a series of classical time invariant digital filter ( pre-treated filter ) and a lower order time variant filter ( adaptive filter ). 本文将原有自适应滤波器分解为一个常规时不变数字滤波器(预处理滤波器)和一个低阶的时变滤波器(TVF)(自适应滤波器)的级联。
A denoising method of seismic data based on iterative time variant filter of discrete Gabor transform 基于离散Gabor变换迭代时变滤波实现地震信号去噪
At the same time, based on the knowledge of digital signal processing, reconstruction by harmonic correction and time variant digital filter was proposed. 与此同时,结合数字信号处理知识,分别用谐波修正和时变数字滤波器的方法,完成基于骨导信号的语音重构。
Decom position of Time - Variant Modal by Time - Frequency Filter 基于时频滤波的时变模态分解方法
The algorithm smoothes magnetic time series using a variant length sliding-window averaging filter, then a PLA representation scheme is employed to extract the feature, which in turn is passed to a threshold detection module. 算法首先将磁敏数据时间序列经过变长滑动窗口滤波预处理,由PLA抽取平滑后的时间序列特征,用于车辆检测,从而获得相关的交通信息。
