Research on Frequency and Timing Synchronization for Orthogonal Frequency Division Multiplexing in DRM System

摘要

Based on the DRM System specification,symbol timing and fractional frequency offset estimation for DRM receiving signal are achieved with the aid of cyclic prefix within the OFDM symbols. The redundancy of the signal is exploited without extra auxiliary data. The algorithm can work well with less bandwidth especially in capturing stage of symbol synchronization and tracking stage of frequency synchronization.
