Abstract: This application discloses a path recovery method and apparatus. The method includes: When an anomaly occurs on a transmission path of a signal, a target adaptive equalization coefficient corresponding to an anomaly type of the transmission path is determined from a plurality of candidate adaptive equalization coefficients that enable an adaptive equalization operation to converge. Then, the adaptive equalization operation is performed on the signal based on the target adaptive equalization coefficient to obtain an adaptive equalized signal. Finally, the transmission path is recovered based on the adaptive equalized signal.
