Deux classes de générateurs de code de pseudobruit (PN) à logique à action anticipée non linéaire (NLFFL) basés sur l'utilisation de portes ET et de logique majoritaire (ML) sont comparées. Les propriétés de corrélation croisée et d'accès multiple par répartition en code (CDMA) des séquences NLFFL correctement conçues se révèlent comparables aux propriétés des codes PN linéaires bien connus. Il est déterminé que la conception de code utilisant des portes ML avec un nombre impair d'entrées est plus facile que la conception avec des portes ET. Ceci est particulièrement vrai lorsque le degré de non-linéarité est important, puisque le problème de non-équilibre, par exemple à la sortie d'une porte ET, peut être évité. Les séquences de type ML sont moins vulnérables aux attaques de corrélation et au brouillage par la séquence m d'un générateur NLFFL

Abstract: Two classes of nonlinear feedforward logic (NLFFL) pseudonoise (PN) code generators based on the use of AND and majority logic (ML) gates are compared. Cross-correlation and code-division multiple-access (CDMA) properties of properly designed NLFFL sequences are found to be comparable with the properties of well-known linear PN codes. It is determined that code design employing ML gates with an odd number of inputs is easier compared with designing with AND gates. This is especially true when the degree of nonlinearity is large, since the nonbalance problem, e. g. , at the output of an AND gate, can be avoided. ML type sequences are less vulnerable to correlation attack and jamming by the m-sequence of an NLFFL generator
