| 摘 要： | 突发通信模式是数字通信的重要方式。在突发通信模式的载波同步问题中．前向频率估计算法因为具有估计速度快，而且不存在挂起现象的优点而得到广泛使用。该文介绍了基于自相关函数的前向频率估计算法的信号模型，分析TFitz算法、L＆R算法、MM算法和分段累加算法四种经典的估计算法的攮本思想并对其进行了数值仿真和性能比较，提出现有算法存在的不足以及在实际应用中的局限性，以期进一步了解并提出计算更加简单、精度更高、估计范围更广的高效频率估计算法。

| Abstract: | Burst-mode transmission is a basilic part in digital communication.Feedforward carrier frequency estimator is widely employed in burst-mode transmission.The signal model of autocorrelation-based feed- forward carrier frequency estimator is introduced and four representative estimators are analyzed.At last simulation results were presented to illustrate the performance of the four estimators,in the hope of motivat- ing the research in the field. |
