Abstract

La présente invention concerne un procédé d'envoi de signal et un émetteur. Le procédé d'envoi de signal comprend : un premier émetteur réalisant un filtrage d'arrêt de bande sur au moins un premier point de fréquence d'un signal d'arrêt de bande, générant un premier signal, ledit point de fréquence étant utilisé pour un second émetteur afin d'envoyer un second signal; et le premier émetteur envoyant le premier signal. Selon le procédé d'envoi de signal et l'émetteur, dans les modes de réalisation de la présente invention, un premier émetteur envoie un premier signal destiné à réaliser un traitement de filtrage d'arrêt de bande sur au moins un point de fréquence, de telle façon que le second émetteur envoie, vers ledit point de fréquence, un second signal. Par conséquent, le premier signal et le second signal n'ont aucune collision de co-fréquences dans le domaine de fréquence, par coordination du point de fréquence d'arrêt de bande du premier émetteur et du point de fréquence envoyé du second émetteur. Ainsi la qualité du réseau est améliorée.
