Abstract

dispositivo e método para estimativa de canal seletiva. uma sequência (200) de símbolos (201-1 a 201-3 e 202-1 a 202-14) é recebida em um primeiro canal. uma contribuição de ruído de um dado símbolo de sincronização (201-2) é estimada; uma contribuição de ruído de referência do pelo menos um símbolo adicional (201-1 a 201-3 e 202-1 a 202-14) é estimada. com base na contribuição de ruído e ainda com base na contribuição de ruído de referência, o dado símbolo de sincronização (201-2) é seletivamente considerado, quando da determinação de um coeficiente de acoplamento de diafonia entre o primeiro canal e o segundo canal.
