Abstract

La présente invention concerne un procédé pour l'estimation d'un rapport signal/interférence (SIR) consistant à: estimer la puissance d'un signal reçu à un premier moment, estimer la puissance d'interférence d'un signal reçu à un second moment précédant le premier moment; et combiner la puissance de signal estimée au premier moment et la puissance d'interférence estimée au second moment pour produire une estimation du rapport signal/interférence au premier moment.
