A noise power measuring system and method for a base station receiver are disclosed. In the system and method, a received signal is despread and the noise power of the despread received signal is estimated. An orthogonal code generator generates a noise power measurement orthogonal code, which is orthogonal to all the orthogonal codes presently being used by the mobile station. A correlator connected to the orthogonal code generator performs a correlation operation between the noise power measurement orthogonal code and the despread received signal. A noise power measurer, connected to the correlator, measures the noise power from the output of the correlator.
La présente invention concerne un procédé et un système de mesure de la puissance du bruit pour un récepteur de station de base. Selon le système et le procédé, un signal reçu est désétalé et la puissance du bruit du signa reçu désétalé est estimé. Un générateur de code orthogonal génère un code orthogonal de mesure de puissance du bruit, qui est orthogonal par rapport à tous les codes orthogonaux actuellement utilisés par la station mobile. Un corrélateur connecté au générateur de code orthogonal effectue une opération de corrélation entre le code orthogonal de mesure de la puissance du bruit et le signal reçu désétalé. Un mesureur de puissance du bruit, connecté au corrélateur, mesure la puissance du bruit à partir de la sortie du corrélateur.
