| 摘 要： | 针对突发条件下线性调制信号的载波频率同步，研究了基于非数据辅助的直接判决引导频偏估计算法和开放环频偏估计方法。研究结果表明，直接判决引导频偏估计算法复杂度较低，适用于对性能要求不高的系统。开放环频偏估计算法计算简单，其复杂度低于直接判决引导频偏估计算法，估计时间短适合突发通信系统。

| Abstract: | Because of the carrier frequency synchronization of linear modulation in burst communication,non-data-aided decision-directed and open-loop frequency estimation algorithms are studied.Research results show that decision-directedness has low computation complexity and is suitable for systems which have low performance requirement.The open-loop method has the advantages of simple computation and low complexity,and can be applied to burst communication systems. |

| Keywords: | burst communication linear modulation frequency offset estimation |
