Fine Timing and Frequency Synchronization for CMMB System
نویسندگان
چکیده
A fine timing and frequency synchronization algorithm is presented for an orthogonal frequency division multiplexing (OFDM) system used in China mobile multimedia broadcasting (CMMB). The presented algorithm could accomplish the timing and frequency offset estimation using the perfect relation of training symbols. The simulation and practice results show the new algorithm could give out fine timing synchronization and accurate frequency offset estimation over AWGN channel and multipath channel. Keyword: OFDM; CMMB; timing synchronization; frequency offset estimation
