A semi blind technique for estimating the carrier frequency offset in OFDM communication systems is presented in this paper. The fractional and integer frequency offsets are esti-mated by employing a few null subcarriers in the rst OFDM symbol in a frame. While the conventional null subcarrier based methods estimate the offset by a single global search, the proposed method employs a two stage estimator, which greatly minimize the computational complexity.

采集到的50Hz电源信号送至信号处理器作为参考信号，该参考信号在信号处理器中需经HILBERT变换变成两路正交正余弦信号X1、X2，然后采用自适应滤波器算法滤掉有用信号中的50Hz信号。(Collected 50Hz power signal to the signal processor as a reference signal, the reference signal in the signal processor requires HILBERT transform into two orthogonal cosine signal is X1, X2, and then filter out the use of adaptive filter algorithm useful signal in the 50Hz signal.)
