Abstract[English]
Systems and methods for generating n × n orthogonal matrices in the Galois field GF(q) that is highly efficient and can handle large values of n and q. This method is based on random selection. In addition, this method can be used to construct paraunitary filter banks over finite fields, in applications such as signal processing. This approach can be useful constructing orthogonal matrices that satisfy specific constraints, making it potentially valuable for applications in coding theory and encryption.[French]
L'invention concerne des systèmes et des procédés permettant de générer n × n matrices orthogonales dans le champ de Galois GF(q) qui est hautement efficace et peut traiter de grandes valeurs de n et q. Le présent procédé repose sur une sélection aléatoire. De plus, le présent procédé peut être utilisé pour construire des bancs de filtres paraunitaires sur des champs finis, dans des applications telles que le traitement de signaux. La présente approche peut être utile pour construire des matrices orthogonales qui satisfont des contraintes spécifiques, ce qui la rend potentiellement utile pour des applications dans la théorie de codage et le chiffrement.
