Research of Synchronization Algorithm for CMMB Signal
Bao Han · Modern Electronics Technique · 2010
As the first system developed by Chinese government for various mobile terminals,the system of CMMB(China mobile multimedia broadcasting) employs the OFDM modulation.At the receiving terminal,it is significant for the performance of the CMMB system to detect the signal precisely and realize the synchronization detection.The synchronization detection of CMMB signal was implemented with two different methods(energy detection and correlation detection).The simulation results show that both of the two methods can realize the synchronization detection even at low SNR.
