Abstract
MéTODO E DISPOSITIVO PARA CANCELAMENTO DE INTERFERêNC IAS. A invenção é um dispositivo e um método para cancelamento de interferências entre sinais com proximidade de freqüências, inerentes à co-localização de terminais multipadrão (A1, A2, A3), em um sistema de comunicação. O sinal interferente é amostrado no sinal interferente (S2) ou no sinal perturbado (S1), depois deslocado por fase e atenuado, de acordo com o nível da perturbação (informações C/N), e somado com o sinal perturbado, de modo a formar um circuito de neutralização que pode cancelar a perturbação.
