CA 2199708

A method and apparatus for producing amplified signals for communications having reduced adjacent channel energy involving generating a first signal having an undesired amount of adjacent channel energy, generating a second signal corresponding to the undesired amount of adjacent channel energy, and subtracting the second signal from the first signal to remove the undesired amount of adjacent channel energy. Several embodiments are disclosed.

Procédé et appareil permettant de produire des signaux amplifiés pour la communication, qui présentent une énergie de canal voisinréduite. Ledit procédé consiste à générer un premier signal ayantune quantité non désirée d'énergie de canal voisin, à générer un second signal correspondant à ladite quantité non désirée d'énergie de canal voisin et à soustraire le second signal du premier signal pour enlever la quantité non désirée d'énergie de canal voisin. Plusieurs modes de réalisation sont en outre décrits.
