查询词典 convolution theorem

The convolution and correlation are identical under a certain condition. In this condition, the interaural cross-correlation coefficient of an anechoic source convolved with the BIRs can be described by the IACC of BIRs and by the effective duration τe of ACF of the anechoic source.

In contrast, the frequency-domain method transforms the time-frequency convolution into product operation in multiple frequency bands, thus has simple com putation and fast speed. As such, it has become a mainstream method for blind deconvolution.

相比之下，频域方法将时频卷积变换为多个频率段上的乘法运算，运算简单，速度快，因此成为盲解卷的主流方法。

The results of simulation experiments for single channel data or arbitrary channel of multi-channel data show the clearer event, the better wave shape and the higher SNR compared with the conventional convolution filter and common SVR based on RBF. So it is possible that SVR based on Ricker wavelet kernel function is applied to suppressing noise in seismic prospecting data.

对单道记录或多道记录中任选道的仿真实验表明，与传统的基于径向基核函数的支持向量回归及褶积滤波方法相比，使用本方法去噪后的同相轴更为清晰，波形恢复得更好，信噪比也较高，因此有可能将其应用于地震勘探记录的去噪处理中。
