Abstract
"APARELHO DE RECEPçãO E MéTODO DE RECEPçãO". Na técnica anterior, quando várias interferências seletivas de freq³ência tendo diferentes graus de influências ocorrem, há uma possibilidade de uma interferência poder ser não-detectada de forma desfavorável. Uma potência média indicando características de canal é extraída de uma unidade de cálculo de valor de referência (7) como um valor de referência. Um nível de interferência correspondente ao grau de influência pela interferência seletiva de freq³ência é extraído de uma unidade de detecção de interferência (8). Uma unidade de determinação de confiabilidade (9) determina um portador que esteve sujeito a uma interferência, com base no valor de referência e no nível de interferência, para decidir um nível de confiabilidade. Uma unidade de correção de erro (6) realiza uma correção de erro de um sinal de demodulação, com base no nível de confiabilidade.
