Abstract

<B>DISPOSITIVO E MéTODO PARA LOCALIZAR UMA ESTAçãO MóVEL EM UM SISTEMA DE COMUNICAçãO MóVEL<D> Um dispositivo e método para localizar uma estação móvel (MS) em um sistema de comunicação móvel. No dispositivo de localização de MS, uma primeira antena e uma segunda antena de uma estação de base (BS) são espaçadas entre si por uma distância equivalente a um comprimento de onda de um canal de transmissão de MS multiplicada por um coeficiente pré-determinado, como um meio. Um primeiro conversor descendente de freq³ência e um segundo conversor descendente de freq³ência convertem sinais recebidos da primeira e da segunda antena em sinais de faixa-base e digitalizam os sinais de faixa-base em dados de amostra de chip. Um primeiro demodulador de canal e um segundo demodulador de canal recuperam os dados de amostra de chip recebidos dos primeiro e segundo conversores descendentes de freq³ência e transmitem informações sobre o início de símbolo e código PN de um sinal de MS específico. Um controlador transmite um código PN para identificar as informações de posição de indicador e a MS específica com base no início de símbolo e nas informações de código PN recebidas do primeiro e do segundo demodulador. Além disso, o controlador pode ser abastecido com informações de código ortogonal do demodulador; neste caso, o controlador transmitirá informações referentes ao código Walsh específico. Um extrator de dados de símbolo extrai dois símbolos da MS específica dos dados de amostra de chip recebidos do primeiro e do segundo conversor descendente de freq³ência, com base no código PN e nas informações de posição de indicador. Um estimador de ângulo incidente calcula o ângulo incidente do sinal recebido da diferença de fase entre os dois símbolos extraídos. Um estimador de localização estima a localização da MS específica com base no ângulo incidente estimado e no retardo de ida e volta (RTD) medido para a MS.
