Abstract

"RECEPTOR DE DIVERSIDADE SEM FIO DE BAIXA POTêNCIA COM MúLTIPLOS PERCURSOS DE RECEPçãO". Um receptor de diversidade de baixa potência inclui pelo menos percursos de recepção, cada um dos quais é designado como um percurso de recepção primário ou secundário. Um percurso de recepção primário está de acordo com as exigências do sistemas (por exemplo, de acordo com as exigências da IS-98D). Um percurso de recepção secundário não está completamente de acordo com as exigências do sistema e é designado para uma potência mais baixa, menor área e custo mais baixo do que o percurso de recepção primário. Para um receptor de múltiplas antenas, os dois percursos de recepção podem ser utilizados para processar simultaneamente dois sinais recebidos provenientes de duas antenas. Para um receptor de antena única, é selecionado ou o percurso de recepção primário ou o secundário, por exemplo, dependendo de se 'interferidores' ou sinais de interferência de grande amplitude são ou não detectados, para processar um único sinal de entrada proveniente de uma antena. O receptor pode incluir percursos de recepção adicionais para bandas de freqüência adicionais e/ou GPS.
