The invention relates to the technical field of wireless communication, and discloses a signal sequence recovery method and system, computer equipment and a storage medium, and the signal sequence recovery method comprises the steps: receiving a target signal sequence transmitted by a signal transmitting end in a satellite communication system, constructing an original optimal sampling point set based on the symbol information of the target signal sequence, constructing an optimal sampling point judgment feature set based on a preset feature type; calculating the information gain ratio of each judgment feature in the optimal sampling point judgment feature set based on the original optimal sampling point set, and screening out the optimal sampling point judgment feature; and determining an optimal sampling point based on the optimal sampling point judgment feature, and performing nonlinear interpolation on the target signal sequence according to the optimal sampling point, thereby realizing symbol synchronization and instant clock recovery in the satellite communication process. According to the invention, by calculating the information gain ratio of each judgment feature in different scenes, the judgment feature with the optimal timing recovery precision, the lowest calculation overhead and the highest robustness can be screened out.
