宽带短波通信OFDM系统同步算法设计
esign of OFDM Synchronization Algorithm for Wideband Shortwave communication
本文通过研究宽带短波信道环境，设计了一种适用于该信道环境的基于训练序列的高效OFDM同步算法。该算法通过一种新型的训练序列，首先利用连续相关峰值进行信号到达预警，然后利用连续相关峰值确定精确同步运算范围，最后在该范围内通过训练序列的顶针特性完成精确同步。论文在宽带短波信道环境下进行了算法定时测度曲线和整体同步性能的仿真分析，定时测度曲线分析表明，本文算法同步稳定可靠，同时由整体同步性能对比仿真结果可以看出，在宽带短波信道条件下本文算法较之之前算法有着更精确的同步性能。
In this paper, a new OFDM synchronization algorithm which is fit for wideband short-wave communication and based on training block is proposed.First, we complete the signal reach forecast by the relevant operations. Then we can get the precise scope of synchronization operations by the relevant operations results. And then we make the accurate relevant operations in the precise scope. This paper makes a simulation of the timing metic and the performance of these synchronization algorithm, and through the contrast, it has been proved that the proposed algorithm has better performance than the existing algorithm.
