%X An improved anti-frequency-offset method by windowing in OFDM systems is proposed. The cyclic prefix added at the transmitter side is first removed at the receiver, and then a new cyclic prefix is appended, finally the "new" signal is windowed by a Nyquist window, which is optimized numerical solution. Numerical results show that the anti-frequency-offset capability of the optimized window is much better than other windows.
