Abstract: Frame synchronization in an OFDM system involves calculating a frame synchronization result as a complementary weighted summation of (i) a matched filtered technique, and (ii) an autocorrelation technique. A preamble of ten short training symbols (five predetermined symbols, repeated twice) is transmitted in an OFDM system to provide a basis for performing the matched filter and autocorrelation techniques. The complementary weighted summation is performed using parameters &agr; and (1-&agr;), in which &agr; belongs to the set of numbers between zero and one. Desirably, &agr; is in the range 0.5 to 0.9. Improved (or at least equivalent) synchronization failure rate and bit error rate performance results, compared with either the matched filter technique and the autocorrelation technique alone.
