Abstract:
A method for estimating a symbol timing offset in an Orthogonal Frequency Division Multiplexing (OFDM) communication system is disclosed. The method includes detecting a channel impulse response within one Fast Fourier Transform (FFT) duration; and estimating a symbol timing offset taking the detected channel impulse response into account. The symbol timing offset estimation includes calculating a channel delay duration depending on the detected channel impulse response; and estimating the symbol timing offset such that the channel impulse response is detected within a guard interval, taking into account the calculated channel delay duration and the guard interval existing in the one FFT duration.
