Timing synchronization in OFDM communications receivers

   
   

An orthogonal frequency division multiplexing (OFDM) receiver is synchronized to a received signal during one of the short symbols of the preamble of the OFDM signal, using a timing synchronizing circuit that derives timing information from timing components generated by a constellation processing circuit which generates the timing components from frequency domain components obtained by performing a Fourier transform on the OFDM signal.

Um receptor multiplexing orthogonal da divisão de freqüência (OFDM) é sincronizado a um sinal recebido durante um dos símbolos curtos do preamble do sinal de OFDM, usando um sincronismo que sincroniza o circuito que deriva a informação do sincronismo dos componentes do sincronismo gerados por uma constelação que processa o circuito que gera os componentes do sincronismo dos componentes do domínio da freqüência obtidos executando um Fourier transforma no sinal de OFDM.
