摘要：
A method for detecting a preamble location in a multiple preamble OFDM (Orthogonal Frequency Division Multiplexing) system is disclosed. An OFDM signal is generated with a plurality of frames, and each of the frames includes symbols and a predetermined preamble symbol. A maximum FDDC (Frequency Domain Differential Correlator) value is computed for each of the symbols in some of the frames. The preamble location in a frame is determined by summing the maximum FDDC value for each symbol at a same frame location in consecutive frames of the OFDM signal.
