摘　　要：基于ML前馈定时算法和Gardner反馈定时算法,设计一种适用于短波突发信号的全数字联合定时同步结构。该联合定时同步结构既具有前馈算法收敛迅速的特点,也具有反馈算法稳态误差小、跟踪能力强的特点。不同信道环境下的仿真实验表明,该联合结构算法的收敛和跟踪性能优良。In this paper we design a full digital combined timing synchronization structure for burst mode shortwave signals based on ML-based feedforward timing algorithm and Gardner feedback timing algorithms.The combined timing synchronization structure possesses the properties of both algorithms in fast convergence and in low steady-state MSE and good tracking performance.Simulative experiments carried out in different channels indicate that the combined structure algorithm has good performances of convergence and tracking.
