Abstract

ao incorporar um sinal em uma subportadora selecionada de uma forma de onda de downlink de múltiplas portadoras de sinalização de dados/controle regular, uma estação base modula o sinal incorporado com um esquema de modulação diferente dos outros dados na forma de onda de downlink. a estação base anula as subportadoras adjacentes para minimizar a interferência em um receptor de ativação de baixa potência de um dispositivo (s) ioe. o dispositivo ioe ativa o receptor de ativação de baixa potência em tempos programados para escutar o sinal. para os sinais de sincronização, o dispositivo ioe corrige um relógio local com base em um valor de correlação do sinal para uma sequência predeterminada. para sinais de ativação, o dispositivo ioe correlaciona o que quer que seja detectado na antena com uma sequência predeterminada e compara o valor de correlação com um limite predeterminado. se o limite for correspondente, o dispositivo ioe registra um sinal de ativação e ativa o transceptor primário do dispositivo. caso negativo, o receptor volta à espera.
