摘要

本文分析了正交频分复用(OFDM)系统的时间同步算法。基于基于PN序列的算法，前人提出了不同的自适应检测阈值设置方法。从理论上分析了这些方法的性能，提出了一种适用于大动态范围信噪比的方法。仿真结果表明，该方法能够满足OFDM系统在多径衰落信道下的需求。

Effect of Adaptive Threshold on Time Synchronization Based on PN Sequences in OFDM System

In this paper, the time synchronization algorithm for orthogonal frequency division multiplexing (OFDM) system is analyzed. Based on the algorithm using PN sequence, different methods of setting adaptive detection threshold have been proposed before. We analyze the performance of the methods theoretically, and propose a method which is suitable for large dynamic range of SNR. The simulation indicates the method can satisfy the demand of OFDM system in multi-path fading channel.
