Abstract

"MéTODO E SISTEMA PARA SINCRONIZAçãO EM UM RECEPTOR DE CHAVEAMENTO DE DESLOCAMENTO DE FREQüêNCIA". A invenção descreve um método e um aparelho para atingir sincronização de tempo durante a aquisição de sinal e para atingir sincronização de freqüência em um receptor de comunicação digital após aquisição de sinal. O aparelho compreende: um mecanismo de recepção adaptado para receber um sinal contendo uma pluralidade de intervalos de dados com uma palavra de sincronismo dentro de cada intervalo de dados transmitido; um correlacionador para formar correlações múltiplas, cada uma correspondendo a um intervalo de símbolo de sincronismo, e para correlacionar o sinal recebido com uma sinusóide de uma freqüência esperada para cada um dos intervalos de símbolo de sincronismo selecionado; um combinador para juntar e combinar as correlações múltiplas sobre um pequeno conjunto de recuos de freqüências de acordo com um índice de modulação FSK e um padrão de símbolo de sincronismo conhecido; um detector de pico que forma um sinal de correlação de sincronismo de acordo com uma amplitude máxima de saída do combinador entre os recuos de freqüência candidatos em cada instante de tempo; um detector de limite que compara, em cada intervalo de tempo, o sinal de correlação de sincronismo a um limite; e um estimador de tempo de símbolo que, após a detecção de que um sinal de correlação de símbolo excedeu o limite, estabelece um tempo de símbolo de acordo com um pico de um sinal de correlação de sincronismo. O aparelho compreende ainda um estimador de recuo de freqüência para formular um recuo estimado utilizando símbolos conhecidos e estimados e uma ferramenta para estimar qualidade para determinar a qualidade do recuo de freqüência estimado utilizando o cálculo da relação sinal-ruído.
