中文摘要：
对于α稳定分布噪声的非平稳信号,仅用频域的一维分析方法是不够的,需要考虑进行二维的时—频域分析方法。在基于传统的短时傅里叶变换（STFT）基础上,针对分数低阶α稳定分布的特性,提出了分数低阶STFT新方法。计算机仿真结果表明,该分数低阶STFT方法能克服传统的STFT方法在对α稳定分布进行时频分析时的性能退化问题,为α稳定分布在时频域的研究开拓了全新的途径。
英文摘要：
It is not enough that only using a dimension analysis method for non-stable signal in alpha stable distribution noise, and can need a two-dimensions time-frequency one. This paper proposed short Fourier transform（STFT） time-frequency analysis method of fractional lower-order alpha stable distribution based on conventional STFT. Simulations show that the proposed method has more excellent performance than conventional STFT in time-frequency analyzing of alpha stable distribution process and is a new one in time-frequency domain research of alpha stable distribution.
