This invention is concerned with a method and apparatus for statistically multiplexing based on orthogonal code hopping multiplexing according to orthogonal code hopping patterns in wired/wireless communication systems in which a plurality of synchronized communication channels coexist through one media. The system comparing a primary communication station and a plurality of second communications includes an orthogonal code hopping pattern generator, a spreader for selecting a corresponding orthogonal codeword in the orthogonal code and data symbols, a comparator & controller for monitoring whether the orthogonal codewords collide and determining whether all the transmitting data symbols to the secondary communication stations are the same in the eallision interval, a transmission controller for perforation (transmission 'OFF') in case that all the corresponding data symbols with the same orthogonal codeword for spreading are not the same, and a transmission power controller for compensating for the loss of average reception energy due to perforation.
L'invention concerne un procédé et un appareil de multiplexage statistique de canaux correspondants par sauts de codes orthogonaux dans un système de communication par fil/sans fil dans lequel plusieurs canaux de communication synchronisés coexistent sur un support unique. Le système comprend une première station de communication et plusieurs stations de communication secondaires, ainsi qu'un générateur de configurations de sauts de codes orthogonaux; un dispositif d'étalement destiné à sélectionner un symbole de code orthogonal correspondant dans le code orthogonal; un comparateur et régulateur de collision destiné à contrôler si les symboles de codes orthogonaux entrent en collision et à déterminer si les symboles de données envoyés aux stations de communication secondaires coïncident dans la zone de collision; une unité d'arrêt de la transmission en cas de collision des configurations de sauts et de discordance des symboles de données de transmission; et un organe de commande de puissance de transmission destiné à compenser une perte d'énergie de réception moyenne.
