| 摘 要： | 基于多尺度小波包变换良好的时频局部分析能力,对一类非高斯噪声——双模噪声的统计特性进行研究。理论分析和仿真表明,小波包检测系统不仅具有计算量小、算法比较简单和实时性较强的特点,而且实现了将非高斯噪声(双模噪声)转化为简单的高斯噪声来处理。

| Abstract: | On the basis of time-frequency analysis capabilities of multi-scale wavelet packet transform,this paper studies statistics of one special of non-Gaussian noise-Bimodal Noise.Theoretical analysis and simulation results show that the wavelet packet inspection system not only has a small amount of calculation,the simple algorithm and the strong real-time characteristics,but also brings out turning non-Gaussian noise（Bimodal Noise）out to be easy Gaussian noise to deal with. |

| Keywords: | wavelet packet transform dual-mode noise gaussian noise statistics |
