Abstract: An OFDM packet is initially detected by auto-correlating short training symbols to generate an initial packet detection signal. The initial packet detection signal may be used to initiate a coarse timing synchronization process, which may use a short symbol matched filter. A coarse timing signal may be generated from at least some of the short training symbols by correlating sampled short training symbols with short filter matched coefficients. The coarse-timing signal may be used to initiate the operation of a fine timing synchronization process, which may use a long symbol matched filter. A fine timing signal may be generated from at least some of the long training symbols by correlating sampled long training symbols with long filter-matched coefficients. The fine timing signal may be used to initiate channel estimation by performing a Fast Fourier Transform (FFT) operation on the long training symbols.
