A method and arrangement in a network entity of delay calibration for an OFDM system in a mobile communication system are disclosed. The delay calibration technique as disclosed includes estimating a time delay difference according to a phase difference between two adjacent sub-carriers, dividing the estimated time delay difference into a coarse time delay and a fine time delay, and compensating the coarse time delay in time domain and the fine time delay in frequency domain respectively. |
