摘要

本文提出了一种新的载波相位同步算法，该算法利用所提出的QD(象限决策)方法，既能恢复剩余的频偏，又能恢复相位偏移。该方法的显著特点是残余载波频偏可以通过使用FFT解调信号来补偿，而不需要GI(保护间隔)或导频。

A novel residual carrier synchronization technique for M-QAM-OFDM in the presence of intercarrier interference

We propose a new carrier phase synchronization algorithm which can recover residual frequency offset as well as phase offset by using proposed QD (quadrant decision) method. The salient feature of this method is that residual carrier frequency offset can be compensated by using an FFT demodulated signal without the aid of GI (guard interval) or pilots.
