| Abstract: | The essence of frame synchronization and the two multiple-frame detection methods, i. e. single-frame majority decision（SFMD）and statistical method have been investigated. Experiments show that the performance of multiple-frame detection can dramatically improve,and the scope of SNR in the multiple-frame detection is wider than that in single-frame detetion. |

| Keywords: | frame synchronization multiple-frame detection maximum likelihood |
