摘要 提出一种大载波频偏下的联合同步策略,帧同步采用差分相关法,载波频偏估计采用精度可调的基于自相关的相干频率估计算法。仿真结果表明,在高斯和多径信道下,该策略用于地面数字电视国标系统均具有较好的性能。 A robust joint synchronization scheme under large carrier frequency offset is proposed, which utilizes differential correlation method for frame detection/synchronization and autocorrelation based precision-adjustable coherent method to estimate frequency offset, Simulation results for DTMB system under AWGN and multi-path channels demostrate the performance of the proposed scheme.
