Bogdan Groza,Lucian Popa,Pal-Stefan Murvaye focus on a connection between behavioral modeling and the decoding of BCH/RS/Goppa codes. In this context, the behavioral modeling approach is attractive because it naturally generates solutions with common factors..We present slight modifications of both the Berlekamp-Massey and the Welch-Berleka作者: Omnipotent 時間: 2025-3-22 08:59

Recursive Construction of Gr?bner Bases for the Solution of Polynomial CongruencesA number of questions in systems theory and coding theory can be formulated as the solution of a system of polynomial congruences in one or more variables. We present a new generalised algorithm, based on Gr?bner basis techniques, that recursively solves a wide class of such problems.作者: glacial 時間: 2025-3-27 04:07 作者: 善于騙人 時間: 2025-3-27 05:16
Connections Between Linear Systems and Convolutional Codesions are worked out in detail. It is shown that bi-infinite support systems are dual to finite-support systems under Pontryagin duality. In this duality the dual of a controllable system is observable and vice versa. Uncontrollability can occur only if there are bi-infinite support trajectories in t作者: palette 時間: 2025-3-27 11:43 作者: 制定 時間: 2025-3-27 14:00

Properties of the Tailbiting BCJR Decodersists of forward and backward recursions that start from the left and right principal eigenvectors of the product of the trellis gamma matrices.
