对Schmidl&Cox算法的分析，提出了一种改进的定时同步方案。该方案

利用前导字的相关性，通过改进同步算法实现接收端的定时同步，在高斯信道和SUI一3信

道环境下进行仿真，结果表明：改进的定时同步方案优于传统方案，能取得良好的定时同步。-Schmidl &　Cox analysis of algorithms, an improved timing synchronization scheme. The program draws on the leading word correlation, the receiving end of timing synchronization through improved synchronization algorithm, Gaussian channel and SUI-3 letter Road environment simulation results show that: improved timing synchronization scheme is better than traditional programs, can achieve good timing synchronization.
