Abstract
MÉTODO PARA TRATAMENTO DE PRECODIFICADOR DE INTERFERÊNCIA ROBUSTO EM CANAIS COM RUÍDO DE IMPULSO. Um aparelho composto por um primeiro transceptor em um escritório central (CO) acoplado a um segundo transceptor em um Equipamento de Premissa de Usuário (CPE), através de uma linha de assinante digital )DSL), um precodificador de interferência acoplado ao primeiro transceptor no CO, e uma entidade de controle de vetorização (VCE) acoplada ao transceptor através de um canal de feedback e ao precodificador de interferência, no qual o segundo transceptor inclui um monitor de ruído configurado para detectar ruído de não interferência em um sinal a jusante do CO para CPE, e qual o primeiro transceptor é configurado para receber um sinal de feedback particular predefinido do segundo transceptor que indica no ruído de não interferência é detectado no sinal a jusante em vez de um valor de erro medido.
