Patent CA-2450458-C (CA)
Title: Systeme et methode de coordination de commande d'alimentation de canal de maintenance sans fil
Inventor: PROCTOR JAMES A JR
IPC: H04B7/005
Filed: 2002-06-11
Granted: 2015-04-07
Abstract: Dans un système de communication sans fil, des canaux sans fil sont maintenus pour rendre possible la communication entre des utilisateurs et la station de base. Souvent, un utilisateur sans fil peut être connecté, mais ne pas recevoir ou envoyer activement des données. Par conséquent, des utilisateurs sans fil peuvent être <= actifs >=, et un canal de trafic de données sans fil leur est attribué afin de transmettre ou de recevoir des informations, ou des utilisateurs sont <= inactifs >=, et ne pas recevoir ni envoyerdes informations. Un utilisateur sans fil peut être maintenu en état <= inactif >= par l'intermédiaire d'une séquence périodique demessages de synchronisation. Un procédé de commande d'un niveau de puissance d'un message sans fil comprend la détermination de la présence de données à transmettre, et le réglage du niveau de puissance du message de synchronisation en fonction de la présence de données. Les messages de synchronisation correspondant à l'état <= inactif >= utilisent un niveau de puissance inférieur aux transmissions en état actif qui, elles, utilisent un niveau de puissance plus élevé. Le système commande la puissance en conséquence de sorte que les messages de synchronisation sont envoyés à un niveau de puissance inférieur lorsqu'il n'y a pas de données. La consommation d'énergie et les interférences sont ainsi réduites.

Abstract: A code division multiple access (CDMA) is a type of spread-spectrum communication system having a plurality of subscriber units and at least one base station. In order for a first subscriber unit to communicate with a second subscriber unit, a transmitter unit of the first subscriber unit imprints a unique code upon transmission and the second subscriber unit includes a receiver, which uses the code to decode the transmission. In addition, each transmitter with a CDMA communication system includes a stream cipher generator for enciphering the voice and data communications. Each receiver within a CDMA communication system contains an identical or similar stream cipher generator, which is used to decipher the received enciphered communication. The present invention relates to a stream cipher generator having a plurality of linear feedback shift registers to produce a stream cipher for increasing security using ciphered messages.
