| Abstract: | According to the analysis of the China Mobile Multimedia Broadcasting(CMMB) system,a solution to the symbol synchronization and carrier synchronization is made,which is fit for hardware implementation.The symbol synchronization and the carrier synchronization are completed by using the correlation of synchronous sequence in both time domain and frequency domain.This program can not only reduce the complexity of the hardware achievement,but also can achieve a very good performance in poor conditions. |
