Spectral leakage and picket fence effect in Fourier transform will affect the accuracy of harmonic analysis under asynchronous sampling. To overcome this defect, a novel algorithm for power system harmonic analysis called Frequency Shifting and Filtering (FSF) algorithm is proposed in this paper. In this method, a reference signal is given to shift the frequency of original signal. And then the filter...
A novel synchronization scheme aiming at the special frame structure of China mobile multimedia broadcasting (CMMB) is presented in this paper. Based on the fact that CMMB system is very sensitive to the synchronization error, this scheme gives a solution which integrates high precision symbol timing recovery, carrier frequency recovery and sampling clock frequency recovery. Simulation results show...
