Abstract:
A method and OFDM receiver for estimating timing offset are provided. The method includes receiving OFDM data to calculate frequency offset between a transmitter carrier frequency and a receiver carrier frequency, determining first timing offset based on the frequency offset, compensating the OFDM data with the first timing offset, estimating a residual common phase based on the compensated OFDM data, determining second timing offset based on the residual common phase, and compensating the OFDM data with the second timing offset, if the frame symbol index exceeds the predetermined data length.
