Abstract

resumo método para reduzir um sinal de ruído de campo próximo em um sinal eletrônico trata-se de sistemas e métodos para cancelar um sinal de ruído de campo próximo. os métodos geralmente envolvem: receber (604), a partir de um primeiro dispositivo de captação acústica (120), um primeiro sinal (214) que compreende um sinal de ruído de campo próximo (206); sintetizar (320, 420, 520, 606) um sinal de réplica (322, 422, 522) que replica o sinal de ruído de campo próximo; e comunicar (608) o sinal de réplica e o primeiro sinal para um processo de cancelamento de ruído de campo distante (150). antes de comunicar o sinal de réplica ao processo de cancelamento de ruído de campo distante, pelo menos uma característica do sinal de réplica é controlada (606) de modo que o processo de cancelamento de ruído de campo distante identifique o sinal de ruído de campo próximo como ruído de campo distante. o processo de cancelamento de ruído de campo distante cancela (610) o sinal de ruído de campo próximo e gera (612) um sinal de saída (360, 460, 560) em que o sinal de ruído de campo próximo tem a amplitude reduzida. 1/1
