摘要
小波分析是一门正在迅速发展的新兴学科。阈值降噪法在信号降噪领域已经得到越来越广泛的应用。本论文首先讨论了小波阈值降噪法的基本原理;其次通过理论分析和MATLAB仿真实验,详细讨论了小波阈值降噪中降噪效果影响的因素。最后,对小波阈值降噪的降噪效果进行了总结。
Wavelet analysis is a rapidly developing area of research. The wavelet threshold de-noising has been widely used in signal de-noising. At first, the thesis introduces principle of wavelet threshold de-noising; Second, the thesis discusses the influencing factors of the wavelet threshold de-noising results by theory analysis and MATLAB simulation in detail. Finally, the thesis sums up the wavelet threshold de-noising results.
