The invention is CDMA quadrature signal technology that controls the transmit power of a CDMA signal (302, 407). The CDMA quadrature signal technology receives a CDMA signal (302, 411), and in response, process quadrature components of the CDMA signal to generate a power control signal (517). The CDMA quadrature signal technology adjusts the gain of the CDMA signal (407) in response to the power control signal (517). A CDMA transmitter (301) transmits the CDMA signal after the gain is adjusted. One example of the CDMA transmitter is a CDMA base station (412). Using the invention, a multi-sector CDMA base station (412) can control power without transferring gain information to base station components for all sectors. The invention eliminates unnecessary data transfer and storage.

L'invention concerne une technique par signal en quadrature AMDC permettant de commander la puissance d'émission d'un signal (302) AMDC. La technique par signal en quadrature AMDC consiste à recevoir un signal (302) AMDC et, en réponse, à traiter les composantes en quadrature du signal AMDC pour produire un signal de commande de puissance. La technique par signal en quadrature AMDC permet de régler le gain du signal AMDC en réponse au signal de commande de puissance. Un émetteur AMDC émet le signal AMDC après réglage du gain. Une station de base (412) AMDC constitue un exemple d'émetteur AMDC. Grâce à l'invention, une station de base AMDC multisectorielle peut commander la puissance sans transférer les informations de gain aux composantes de la station de base pour tous les secteurs. L'invention permet d'éliminer le transfert et le stockage de données inutiles.
