SIGNAL GAIN CONTROL METHOD, RECEIVER, AND RELATED APPARATUS

Provided in the embodiments of the present application are a signal gain control method, a receiver, and a related apparatus. The method may comprise: determining a signal in a target frequency band from among received signals in N frequency bands, wherein N is a positive integer greater than or equal to 1, and the signal in the target frequency band is a signal that has a level greater than a preset threshold value or a signal that has interference; before the signal in the target frequency band is combined with a signal in another frequency band, performing gain control on the signal in the target frequency band according to a control signal, so as to obtain a gained signal, wherein the control signal is a preset external control signal or is determined according to the signal in the target frequency band; and performing automatic gain control and linearization control on a combined signal, wherein the combined signal comprises the gained signal in the target frequency band and the signals in the N frequenc
