The circular convolution, also known as cyclic convolution, of two aperiodic functions (i.e. Schwartz functions) occurs when one of them is convolved in the normal way with a periodic summation of the other function.

时频分析中的cohen类中最基本的双线性时频分布式wigner-ville分布，由于在该分布中不含窗函数，因此避免了短时窗傅里叶变换时间分辨率、频率分辨率相互牵制的矛盾(Time-frequency analysis of the Cohen class of bilinear time-frequency distribution is the most basic Wigner-Ville distribution, because the function in the distribution is not included in the window, so as to avoid the contradiction of short-time window Fourier transform time resolution, frequency resolution of each other)
