摘要
This paper presents a now kind of trigonometric spline wavelet on the interval on the basis of trigonometric spline function. The proposed method has more advantages than any other traditional methods, such as symmetry and anti-symmetry-linear phases or generalized linear phases, good time-frequency locality, short support, semi-orthogonal. In the numerical experiment, the trigonometric spline wavelet is applied to Electrocardiogram (ECG) detection. It shows stronger capability of getting more concentrated information in singular position than other wavelets. Therefore, the accuracy of detection is improved greatly.
