针对基于Wigner-Ville分布存在受噪声影响大,存在交叉干扰项的缺点,提出其改进算法平滑伪Wigner-Ville分布和重排谱图应用其中,应用平滑伪Wigner-Ville分布处理其信号间的交叉项和受噪声污染的问题,后结合重排谱图提高其分析精度。
Aiming at the shortcomings that the Wigner-Ville distribution is affected greatly by noise and crosstalk, the improved algorithm is proposed to apply the smoothed pseudo Wigner-Ville distribution and the rearranged spectrum. The smoothed pseudo Wigner-Ville distribution is used to process the crossings between the signals And noise pollution problems, combined with rearrange the spectrum to improve its analysis accuracy.
