| 摘 要： | 提出一种以空间换取时间的方案，能有效提高分数域时频分析的运算效率。鉴于该算法对时间域进行切割，将导致时频分布在衔接处出现边界效应，文章还提出错位平滑技术，有效将各时间段的时频分布进行无缝拼接。 |
| 关 键 词： | 分数域时频分析 空换时技术 时间复杂度 错位平滑技术 FrFT |

| Abstract: | A Gabor technology based space time transformation strategy that can enhance the efficiency of fractional domain time frequency analysis was proposed. Dislocation smoothing technology was presented to overcome the boundary effect between the joint parts in splitting the time domain. The simulation results show that the algorithm can enable the seamless joining of the splitted time frequency distributions. |
| Keywords: | fractional domain time frequency analysis space time transform technology time com-plexity dislocation smoothing technology fractional Fourier transform(FrFT) |
