| 摘 要： | 结合IEEE802.16m协议分析了定时同步误差对系统性能的影响。通过对同步训练序列及传统定时同步算法的分析,提出了一种适合IEEE802.16m系统的定时同步方案。该方案利用训练序列的相关性,通过改进前导字结构及同步算法实现接收端的定时同步。在高斯信道和SUI-3信道下进行了仿真。结果表明,改进的定时同步方案优于传统方案,具有良好的性能,且易于实现。

| 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... |
