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."APPARATUS AND METHOD FOR DETECTING FRAME AND SYMBOL TIME SYNCHRONIZATION". The present invention relates to an apparatus and method for detecting time synchronization of a frame and symbols. The apparatus includes: a correlation filter, obtaining a correlation value between a predetermined time domain local phase reference symbol and the digital signal; a maximum value detector detecting a position of a maximum value of correlation filter outputs; a frame synchronizer, seeking a frame starting point from the maximum value position; and a symbol timing synchronizer, synchronizing the symbol timing of the board from the maximum value position.
