Apparatus and method for detecting preamble packet in orthogonal frequency-division multiplexing system |
摘要 |
There is provided an apparatus for detecting a preamble packet in an orthogonal frequency-division multiplexing (OFDM) system, including: a cross-correlation calculating means for calculating a cross-correlation value between a received signal and previously stored preamble pattern values for an OFDM symbol region (N-point); a delay means for delaying the calculate cross-correlation value as much as a M-point interval; a receiving power measuring means for measuring a receiving power for the guard interval; and a dividing means for calculating a final cross-correlation value by dividing the delayed cross correlation value by the measured power.
