In one or more embodiments, an over-sampling method and corresponding over-sampling circuit efficiently generate an over-sampled signal by determining sampling phases in the over-sampled signal that are unused by downstream processing of the over-sampled signal, and skipping the generation of output values for the over-sampled signal that correspond to the unused sampling phases. In a communication receiver embodiment, determining the unused sampling phases comprises, with respect to currently estimated multipath delays of a received communication signal from which the over-sampled signal is derived, determining which sampling phases in the over-sampled signal will not be used by a downstream processing circuit having known processing delay assignment constraints. The known delay assignment constraints comprise Rake finger placement constraints or channel equalizer tap placement constraints, for example.

La présente invention concerne, dans un ou plusieurs modes de réalisation, une méthode de sur-échantillonnage et le circuit de sur-échantillonnage correspondant générant de manière efficace un signal suréchantillonné en déterminant les phases d'échantillonnage du signal suréchantillonné qui ne sont pas utilisées lors de son traitement en aval et en ignorant la génération de valeurs de sortie du signal suréchantillonné qui correspondent aux phases d'échantillonnage non utilisées. Dans un mode de réalisation avec récepteur de communication, déterminer les phases d'échantillonnage non utilisées implique, en ce qui concerne les retards à voies multiples estimés d'un signal de communication reçu et à partir duquel un signal suréchantillonné est dérivé, déterminer quelles phases d'échantillonnage du signal suréchantillonné ne seront pas utilisées par un circuit de traitement en aval connaissant les contraintes d'affectation des retards de traitement. Les contraintes d'affectation de retard connues couvrent par exemple les contraintes de placement d'un doigt Rake ou d'un dispositif d'égalisation des canaux.
