Abstract

<B>MéTODO E SISTEMA DE LOCALIZAçãO DE UNIDADE MóVEL DE ASSINANTE (MS) EM UM SISTEMA DE CODIFICAçãO DE CANAL DE ESPALHAMENTO ESPECTRAL<D> Método e sistema de localização de unidade móvel de assinante (MS), num sistema de codificação de canal de espalhamento espectral, utilizam um canal conhecido de radiotransmissão de localização de espalhamento espectral (34), que é multiplexado por divisão em tempo, com canais normais multiplexados por divisão em código (36). Cada estação base (12, 14 e 16), numa área definida de serviço, transmite o sinal conhecido de radiotransmissão de localização de espalhamento espectral multiplexado por divisão em tempo (34), como por exemplo, um canal de localização conhecido, como um sinal de radiotransmissão de localização de espalhamento espectral, num mesmo intervalo de tempo. As unidades móveis de assinante (18) recebem o sinal do radiotransmissor de localização de espalhamento espectral (34), multiplexado por divisão em tempo, com os canais normais de CDMA (36) e determinam suas próprias localizações usando técnicas de localização, como por exemplo, trilateração. De preferência, toda a potência de transmissão de uma estação base é designada para este canal especial e conhecido de localização (34) durante a transmissão.
