ABSTRACT:
To synchronize symbol timing in a communication system, time-domain signals are generated by performing an IFFT on frequency-domain signals. Positions of power peaks are detected by analyzing a channel impulse response (CIR) of the time-domain signals. Channel state informations are provided by analyzing a channel state, such that each channel state information corresponds to each position of the power peaks. A proper symbol start position is determined based on the channel state informations.
