Coding information by walsh matrices
The representation of the general linear group GL(n, 2) by the automorphism subgroup GL(N, 2) under the multiplicative notation in its action in the space RN, where N = 2n, is considered. Each matrix as an element of the group GL(n, 2) defines ordering: the group Zn and its group of characters, which are popular in digital processing of information in the form of discrete Walsh functions. On the basis of the fast Walsh transform and this correspondence the authors created a software prototype of an automatic output signal coding system. The essence of the proposed software product is the number of possible permutations, which is calculated by the formula (2n - 20)(2n - 21)... (2n - 2n-1) for n-th order matrices. Based on the program, it is possible to organize a multi-channel system of reconfigurable decoders when transmitting hidden information over open communication channels.
