Realization of Continuous Wavelet Transform of Sequences by MATLAB
Yuanying Zhao · Journal of Sichuan University · 2006
The program realization of continuous wavelet transform(CWT) by MATLAB is analyzed.Firstly,the basic concept of wavelet transform and the arithmetic of CWT in MATLAB is introduced.In this arithmetic,the error caused by differential coefficient is found,and it is a great disadvantage for analyzing signals.Therefor a new arithmetic of CWT is showed.Finally,take FSK signal as an example to make continuous wavelet transform using two arithmetics and analyze the result in theory.It shows the new arithmetic is better than the arithmetic in MATLAB.
