Abstract

Divers modes de réalisation de la présente invention se rapportent à un dispositif et à un procédé de réduction d'interférence harmonique dans un dispositif électronique. Le dispositif électronique peut comprendre : un premier circuit de communication et un second circuit de communication qui comprennent une pluralité de trajets de réception ; et au moins un processeur. Le processeur, lorsqu'une première fréquence utilisée pour la communication d'un premier réseau, et une seconde fréquence utilisée pour la communication d'un second réseau présentent une relation de multiplication, identifie si une interférence harmonique se produit en raison de la communication du second réseau ; et, lorsqu'il est déterminé que l'interférence harmonique s'est produite en raison de la communication du second réseau, change un premier trajet de réception du premier réseau à un second trajet de réception, différent du premier trajet de réception. D'autres modes de réalisation sont également possibles.
