  • 例句与用法
  • However, wigner-ville distribution is n't enough effective applied to multicomponent signals processing for existing crossed items, sometimes signal items completely ca n't be distinguished from distribution for serious disturbance of crossed items . in addition, we can utilize the wigner-ville distribution to reduce the random noise of signals in that wigner-ville distribution is n't enough sensitive to noise . in theory, radon-wigner transform of lfm signals produces a distinct maxima ( peak ) in the radon-wigner plane, so it describe effectively the feature of the lfm signals and suppress effectively the crossed items along with wigner-ville distribution . we can utilize the radon-wigner transform to reduce the random noise of lfm signals in that the noise distrbute as dot at random in the radon-wigner plane
    另外,维格纳-威利分布是完全有噪的,但它对噪声是不敏感的,因此可以利用维格纳-威利分布实现对含噪信号的去噪处理。理论上线性调频信号的radon-wigner变换在radon-wigner平面上以尖峰形式表现,因此radon-wigner变换能够有效描述线性调频信号的物理特征,抑制在维格纳-威利分布中产生的交叉项。在radon-wigner平面中随机噪声是呈点状随机散布开的,因此利用radon-wigner变换还能对含噪线性调频信号进行去噪处理。
