Symbol synchronization in a communication system is carried out as follows. A plurality of symbols corresponding to a transmitted signal is received, where the plurality of symbols include guard intervals. Peak correlation is obtained using the plurality of received symbols. The second derivative of the peak correlation is obtained, and one or more peaks within a corresponding guard interval are identified from the second derivative. A symbol start time for each received symbol is estimated based on the second derivative of the peak correlation.
