The invention discloses a method of orthogonal code group generation and orthogonal code group conversion used in any of which contains code division multiple access (CDMA), spread spectrum techniques and digital communication system. It causes any length of non-zero real-number and complex-number sequence to be an orthogonal code group by the way of orthogonal rotation. And it converts any real-number and complex-number orthogonal code group into a plurality groups of orthogonal code groups which characteristics are substantially identical to those of the initial code group through the orthogonal rotation conversion. The codes before and after the conversion are orthogonal each other to satisfy various requirements in code division multiple access (CDMA), spread spectrum techniques and digital communication system.

L'invention concerne un procédé de génération d'un groupe de codes orthogonaux et de transformation orthogonale du groupe de codes mis en oeuvre dans un système de communication numérique à AMRC quelconque faisant intervenir la technique de l'étalement de spectre. Grâce au procédé de rotation orthogonale, une séquence de nombres réels et de nombres complexes différents de zéro génère un groupe de codes orthogonaux, quelle que soit la longueur de la séquence. Par la suite, le groupe de codes orthogonaux de nombres réels ou complexes quelconques est soumis à la transformation par rotation orthogonale et une pluralité de groupes de codes d'origine essentiellement identiques aux codes orthogonaux sont générés. Les codes avant et après la transformation sont orthogonaux de manière à satisfaire aux exigences du système de communication numérique AMRC faisant intervenir la technique de l'étalement du spectre.
