| Abstract: | Based on IEEE802.16m, this paper analyzes the timing synchronization error on system performance. Then it proposes a timing synchronization scheme through analyzing the synchronization training sequence and traditional timing synchronization algorithm. This scheme uses the correlation of training sequence and achieves the timing synchronization in receiver, through improving preamble architecture and synchronization algorithm. Finally, the results in the Gauss channel and SUI-3 channel simulation environment show that the proposed scheme which is better than traditional scheme has better performance and can be implemented easily. |
