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 symbol , 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 collision 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.
La présente invention concerne un procédé et un appareil de multiplexage statistique selon le multiplexage 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 de comparaison d'une station de communication principale et de plusieurs stations de communication secondaires comprend un générateur de configurations de sauts de codes orthogonaux, un dispositif d'étalement destiné à sélectionner un mot-code orthogonal dans le code orthogonal et le symbole de données, un comparateur et régulateur pour contrôler si tous les mots-codes orthogonaux entrent en collision et déterminer si tous les symboles de données envoyés aux stations de communication secondaires coïncident dans l'intervalle de collision, une unité d'arrêt de transmission si tous les symboles de données correspondant au même mot-code orthogonal pour l'étalement sont en discordance, et un organe de commande de puissance de transmission destiné à compenser une perte d'énergie de réception moyenne.
