Wavelet Analysis Method of Signal in α Stable Distribution
Yubao Gao, Chen Ding · Jisuanji gongcheng · 2012
It is not enough that only using a dimension analysis method for non-stable signal in α stable distribution noise.A novel wavelet time-frequency analysis method of fractional lower-order α stable distribution is proposed in this paper based on conventional wavelet,which includes the idea combining traditional wavelet and spectrum analysis.Simulations show that the proposed method has more excellent performance than conventional wavelet in time-frequency analyzing of α stable distribution process.
