On the general classification of nonlinear filters of m-sequences
A representation for nonlinear filters of m-sequences, the Sequential Decomposition in Cosets, is presented. This representation identifies every kth-order nonlinear filter with the sum of the characteristic sequences corresponding to every coset of weight less than or equal to k. In this way, the structural properties of the nonlinear filters can be easily studied. (C) 1999 Elsevier Science B.V. All rights reserved.
