Provided are a channel tracking method and a related device therefor, which are used in the technical field of communications. The method comprises: a receiver receiving at least two tracking signals sent by a transmitter, wherein the tracking signals are used for the adjusting of DFE coefficients of a decision feedback equalizer by the receiver; the receiver obtaining a first DFE coefficient and a second DFE coefficient according to the at least two tracking signals; the receiver instructing, according to the first DFE coefficient and the second DFE coefficient, the transmitter to adjust the sending frequency of the tracking signals; and the receiver changing the sending frequency of the tracking signals according to the change amount of the DFE coefficients at adjacent moments. When a channel is unstable, the sending frequency of a tracking signal can be increased, thereby influencing the updating speed of a DFE coefficient, such that a receiver can restore a received signal more accurately, and it can be e
