Kernel-factorization deconvolution method
F.N. Kong, Ziang Li · IEEE Transactions on Acoustics Speech and Signal Processing · 1990
The deconvolution problem for a cycle convolution equation with the input (or the deconvolution kernel) spectrum containing zeros is discussed. It is shown that through factorization of the kernel the impulse can be obtained by combined use of the two conventional methods: the Z-transform division method and DFT (discrete Fourier transform) division method, if the length of the impulse response is>
