Symbol and Clock Synchronization Scheme in CMMB System
Abstract
In this paper,a novel symbol and clock synchronization scheme for Orthogonal Frequency Division Multiplexing(OFDM)-based China Mobile Multimedia Broadcasting(CMMB) is presented.Based on the fact that CMMB system is sensitive to the symbol and clock synchronization error,this paper gives a solution which uses the beacon of slot and Cycle Prefix(CP) to catch and tracing the window position.Clock error estimate is done with scatter pilot of OFDM symbol.The Root Mean Square Error(RMSE) of sampling time error is calculated as the standard of the scheme performance.Simulation results show the scheme is effective and feasible.
