摘要：
We describe a new method of frequency-domain deconvolution when the kernel has no spectral inverse. Discrete frequency interpolation is used to avoid zero-valued frequency samples. The algorithm does not suffer from the spectral singularities of the original kernel, its complexity is proportional to the fast Fourier transform, and a comparative noise study showed improved performance relative to the direct frequency-domain method.
