Abstract

"APARELHO E MéTODO PARA DETECTAR SINCRONIZAçãO DE TEMPO DE QUADRO E SìMBOLO". A presente invenção refere-se a um aparelho e um método para detectar sincronização de tempo de um quadro e símbolos. O aparelho inclui: um filtro de correlação, obtendo um valor de correlação entre um símbolo de referência de fase local em domínio de tempo predeterminado e o sinal digital; um detector de valor máximo, detectando uma posição de um valor máximo de saídas do filtro de correlação; um sincronizador de quadros, buscando um ponto de partida do quadro a partir da posição do valor máximo; e um sincronizador de cronometragem de símbolos, sincronizando a cronometragem de símbolos do quadro a partir da posição do valor máximo.
