Abstract

Un système de communication assurent un multiplexage temporel appliqué à l'utilisation de codes d'étalement. Le système de communication accepte des informations (301, 302) d'au moins deux utilisateurs et code chaque information d'utilisateur à l'aide de codeurs (303, 306) de correction d'erreurs. Les informations codées sont ensuite multiplexées par un multiplexeur (312) dans des tranches de temps. La sortie du multiplexeur (312) est étalée par un code d'étalement commun (Walsh), brouillée avec une séquence de pseudo-bruit et dirigée vers un modulateur pour transmission. De cette manière, les informations pour deux utilisateurs peuvent être transmises en utilisant un seul code d'étalement (Walsh).
