摘要
本文介绍了离散小波变换的原理及其在处理非平稳信号时的优势。通过使用离散小波变换对输入的带有间断点的信号进行分析,给出了经过小波变换的结果的图形并进行了分析。本实验硬件平台使用TMS320C5509APGE开发板。
This paper introduces the principle of discrete wavelet transform and its application in the treatment of non-stationary signal. By using the discrete wavelet transform on the input signal with discontinuity points, the graph and analysis are given accord to the results of discrete wavelet transform and a graphical analysis. Hardware platform used in this experiment is TMS320C5509APGE development board.
