rpk的音标

A new adaptive kernel function, named the radial parabola kernel ( RPK), is proposed, the RPK can adopt the optimizing method to filter cross-terms adaptively according to the signal distribution, obtain good time-frequency resolution, and offers improved TFD for a large class of signals.

该核函数可根据被分析信号的不同特性，采用优化方法自适应对模糊函数进行低通滤波，最大程度地滤除交叉干扰项，提高时频分辨率，具有对信号的广泛自适应性。

And thus the fine time-frequency resolution can be obtained. The RPK time-frequency distribution not only suppresses the cross-terms preferably but also removes the noise of signals due to the adaptive filtering of the kernel function.

自适应抛物线核时频分析方法由于核函数对信号自项的选通作用，不仅较好地抑制了交叉项，同时对噪声起到了很好的抑制效果。
