CA 2513318

An arrangement estimates the uplink SINR of a CDMA channel. It includes means (40) for estimating the signal power using the channelization code of the channel. A selector (28) searches for and selects an idle channelization code that is orthogonal to the channelization code of the channel. This idle code is used by further means (30) for estimating the power of interference plus noise. Means (42) then form the SINR estimate using these estimates.

La présente invention concerne un dispositif évaluant le rapport signal/brouillage plus bruit de liaison montante d'un canal CDMA. Ce dispositif comprend un moyen (40) conçu pour évaluer la puissance du signal au moyen du code de découpage en signaux du canal. Un sélecteur (28) recherche et sélectionne un code de découpage en signaux libres qui soit orthogonal au code de découpage en canaux du canal. Ce code libre est utilisé par un autre moyen (30) conçu pour évaluer la puissance totale du brouillage et du bruit. Un moyen (42) élabore ensuite l'évaluation SINR au moyen de ces évaluations.
