Abstract

captura-se uma pluralidade de amostras de dados durante um único período de captura usando uma cadeia de recepção de wlan, em que as amostras de dados incluem um sinal de interesse periodicamente transmitido por uma wwan. um estado de ganho de lna preferencial é selecionado dentre uma pluralidade de estados de ganho de lna disponíveis para a cadeia de recepção de wlan. a pluralidade de estados de ganho pode ser um conjunto discreto de estados de ganho de lna ou pode ser um conjunto de estados de ganho de lna derivados a partir de medições de energia. o estado de ganho de lna da cadeia de recepção de wlan é ajustado para o estado de ganho de lna selecionado e as amostras de dados são capturadas durante cada um dentre a pluralidade de tiques de captura contíguos dentro de um período de captura. as amostras de dados capturadas são processadas para detectar o sinal de interesse.
