Abstract

modalidades da presente invenção descrevem um método para obter o tempo de chegada toa quando um terminal móvel é localizado, incluindo: receber (s102) um sinal de referência de localização enviado por um transmissor de localização; realizar (s104) o processamento relacionado ao domínio de tempo no sinal de referência de localização e uma sequência de sinal de referência de sincronização para obter um valor de espectro relacionado de um componente de sinal de múltiplos trajetos que corresponde a um valor de retardo; detectar (s106) um parâmetro de canal usado quando o sinal de referência de localização é recebido, e gerar, de acordo com o parâmetro de canal e uma função que diminui progressivamente com o valor de retardo, um limiar de espectro relacionado que diminui progressivamente com o valor de retardo; e atravessar (s108) o valor de retardo em ordem ascendente do valor de retardo, pesquisar por um primeiro valor de retardo atravessado cujo valor de espectro relacionado de um componente de sinal de múltiplos trajetos que corresponde ao valor de retardo é maior do que um limiar de espectro relacionado que corresponde ao valor de retardo, e usando o valor de retardo encontrado como o toa para emissão.
