Abstract :
A new fast time synchronization technique is proposed for DVB-H receiver in this paper. Only one DVB-H OFDM symbol is needed to achieve accurate time synchronization by using the correlation function of the received signal and four time-domain local references generated from the DVB-H scattered pilots. The computation complexity of the new algorithm is further reduced by limiting the range of correlation function, which is realized by exploiting the cyclic property of the OFDM signal
