摘要
提出了一种利用恒包络零自相关(CAZAC)序列和循环前缀相结合的OFDM系统的同步算法.对基于CAZAC序列的OFDM同步算法进行了分析,指出了该方法的缺点所在.并考虑到训练序列中循环前缀对同步性能的影响,对利用CAZAC序列和循环前缀相结合的同步算法进行了计算机仿真.结果表明,同步性能得到明显提高.
A synchronization algorithm for OFDM is proposed by combination of CAZAC sequence and CP. An analysis was made on the synchronization algorithm with only CAZAC sequence considered, and its disadvantages were pointed out. Considering the effect of CP on the synchronization, the algorithm combining the ＇CAZAC sequence and CP can considerably improve the synchronization performance. Computer simulations verify the expected goal.
