bispectrum

基本解释

The concepts of bispectrum and AR model are discussed.
讨论了双谱和目标信号建模的相关概念；
As one high order spectrum estimation, bispectrum estimation is widely used.
双谱估计是一种应用广泛的高阶谱估计。
The integrated bispectrum revealed the character of gear flake successfully.
并得出了Wigner高阶谱在时频域中满足的一些性质，只有当Wigner高阶谱满足这些物理性质时，使用其才是有物理意义的。
Integrated bispectrum is another solution for the problem of bispectrum.
利用积分双谱成功的提取出了齿轮出现剥落的故障特征。
The simulation shows that the order bispectrum analysis is superior to the traditional bispectrum.
仿真显示该方法优于阶比谱和传统双谱。
