摘　　要：OFDM系统的接收端对同步精度有着很高的要求,同步误差会导致系统性能的急剧下降。本文对基于训练序列的三种同步进行了仿真分析,并引入错误概率,在不同信噪比下分析各个算法的同步精度,对符号同步的深入研究有参考价值。The receiving end of OFDM system has a. very high request to the synchronized precision, Synchronization error will lead to a sharp drop of system performance. In this paper,three arithmetics have been simulated The error probability has been introduced . We also analyzed the synchronization accuracy under different signal to noise ratio. This paper would be a valuable reference of the deed research in svmbol Svnc, hronization.
