Abstract

<B>SISTEMA DE POSICIONAMENTO LOCAL<D> Um sistema de posicionamento local (LPS) usa os parâmetros de propagação de rádio em uma ligação de emissão de CDMA ou em uma ligação reversa de TDMA, para estabelecer uma posição da estação de base. A estação móvel recebe sinais de canal piloto a partir de pelo menos três estações de base distintas, e registra, o deslocamento de chip PN dos sinais de canal piloto. A diferença de tempo LPS da abordagem de triangulação de chegada não exige capacidades adicionais de detecção de sinal. As estações de base enviam sinais de canal piloto que chegam em uma estação móvel com uma fase específica e pelo menos uma intensidade mínima predeterminada. A estação móvel informa de volta os sinais de canal piloto ''visíveis'', suas fases e intensidade de sinal para o LPS que usa um sistema não-linear de localização, expresso como um conjunto de funções de custo, para estimar a localização da estação móvel. O LPS pode também resolver o problema de localização de estação móvel de telefone de emergência para sistemas de CDMA sem fio mediante determinação da posição de uma pessoa em situação difícil que tem um telefone celular digital.
