Unlike the traditional kernel function methods to suppress cross terms, our method not only reduces the interfering cross-terms but also preserves the superb time-frequency concentration of the WVD.

不同于传统的抑制交叉项的核函数方法，该方法抑制交叉项的同时，保持WVD了高时频聚集性。

The printk function and dmesg methods are common means for kernel debugging.

printk 函数和 dmesg 方法都是用来进行内核调试的常用方法。

Different from the existing kernel feature extraction methods, the kernel function used in the proposed one is not required to satisfy Mercers theorem so that they can be chosen from a wide range.

与现有的核特征抽取方法不同，该方法不需要核函数满足mercer定理，从而增加了核函数的选择范围。
