A HOS-based blind deconvolution algorithm for the improvement of time resolution of mixed phase low SNR seismic data by A.F.M., Hani, M.S., Younis, M.F.M., Halim

“…This modification reduces the effect of the availability of a small number of samples and strong additive noise on the cumulant slices. These modifications are found to improve the overall deconvolution performance, with approximately a five-fold reduction in a mean square error (MSE) and a six-fold reduction in convolution noise of 10 dB of the SNR. …”
