Patent ID: 8300623

Claim:
A frame synchronization method of an OFDM receiver comprising: a symbol synchronization step of obtaining a synchronization timing for each OFDM symbol by executing calculation of correlation in the symbols on the basis of an autocorrelation factor included in each OFDM symbol transmitted from wireless base stations; a unique symbol correlation search step of obtaining timing of a notification channel by executing calculation of correlation for a unique symbol included in the notification channel; a notification channel decoding step of executing decoding of the notification channel or a channel synchronized with the notification channel on the basis of timing when a degree of correlation obtained by the unique symbol correlation search is highest; and a notification channel decoding step of executing decoding of the notification channel on the basis of timing when a degree of correlation obtained by the unique symbol correlation search is second highest in a case where an error exists as a result of error detection executed after the notification channel decoding step.
