摘要：Provided is a frequency and time offset estimation method and apparatus usingthe same for an orthogonal frequency division multiplexing (OFDM) communicationsystem. The invention can establish frequency and time synchronization while improvingdata transmission rate in the OFDM communication system by estimating a time offsetand a decimal of frequency offset using a first OFDM symbol and a Cyclic Prefix (CP) of anOFDM frame and compensating a received signal based thereon in a time domain, andestimating an integer of the frequency offset using the compensated signal and againcompensating the compensated received signal based on the estimated integer of thefrequency offset in a frequency domain.
