Abstract

esquemas de sincronização de quadros de enlace descendente robustos em redes sem fio cdma para geolocalização um sistema de localização sem fio é configurado para funcionar em uma rede de comunicações sem fio baseada em cdma em modalidades exemplares, unidades de medição de localização (lmus) podem sincronizar-se com setores de estações base e armazenar informação de temporização de setor. em resposta a uma solicitação para geolocalizar um dispositivo móvel que se comunica com um setor, informação de temporização de setor para o setor servidor é enviada a outras lmus e as lmus podem utilizar a informação de temporazição de setor para detectar sinais de enlace ascendente transmitidos pelo dispositivo móvel. a localização do dispositivo móvel pode ser então estimada com base em medições de tempo de chegada feitas pelas lmus
