针对突发通信的定时同步问题，提出一种基于正弦波形的快速定时同步算法。利用四个平均幅值点确定一条正弦曲线估计出定时误差，既能够实现4倍符号速率的定时同步，又避免了传统最大似然估计法需要进行的大量乘法运算，能够实现定时误差的快速估计。最后利用MATLAB进行Monte Carlo仿真实验，仿真结果表明新算法不仅具有低的复杂度，还具有高的估计精度。

A fast timing synchronisation algorithm based on sine wave is proposed in this paper for the issue of timing synchronisation in burst communication.Four average amplitude points are utilised to determine a sine curve to estimate the timing error,thus it can both achieve timing synchronisation at four times of the symbol rate,and avoid large number of multiplication operation the traditional maximum likelihood estimation required,and can implement a fast estimation on the timing error.At last MATLAB is used to carry out Monte Carlo simulation experiment,the simulation results show that this new algorithm has low complexity and high estimation accuracy both.
