Noise measurements are made within a fraction of a single symbol period of a longest orthogonal code symbol. A control processor (520) identifies an unoccupied code having a spreading factor that is less than a longest spreading factor for the system. A despreader (512) measures symbol energy based on the unoccupied code and a noise estimator (516) generates noise estimations based on the measured symbol energies. The subscriber station uses similar techniques in order to perform channel estimations within a period that is a fraction of a symbol period of a longest-spreading-factor code.

Selon l'invention, des mesures de bruit dont réalisées dans une fraction d'une période de symbole unique d'un symbole de code orthogonal le plus long. Un processeur de contrôle (520) identifie un code non occupé présentant un facteur d'étalement plus court qu'un facteur d'étalement le plus long pour le système. Un dispositif de désétalement (512) mesure l'énergie du symbole sur la base du code non occupé et un estimateur de bruit (516) génère des estimations du bruit sur la base des énergies de symbole mesurées. La station d'abonné utilise des techniques similaires pour réaliser des estimations de canal dans une période qui est une fraction d'une période de symbole d'un code à facteur d'étalement le plus long.
