TL;DR: A sequency difference detection and correction (s.d.c.c.) system is described which enables the partial correction of transmission errors in a Walsh-Hadamard transform image to be achieved without channel coding.
Abstract: A sequency difference detection and correction (sddc) system is described which enables the partial correction of transmission errors in a Walsh-Hadamard transform image to be achieved without channel coding Using a first-order two-dimensional random Gaussian Markov field as the image, the percentage mean-square error in the recovered signal is reduced with the aid of the sddc system by two orders of magnitude for transmission error rates <3%
