Abstract: Embodiments of this application provide a receive end apparatus. The receive end apparatus includes a trans-impedance amplifier TIA, a control apparatus, and a first storage module. The control apparatus is configured to receive a signal transmit identity of a first signal, and determine, based on a correspondence that is between a signal transmit identity and a gain and that is stored in the first storage module, a first gain corresponding to the signal transmit identity of the first signal, where the signal transmit identity indicates a transmit end apparatus of a signal or a channel for receiving the signal. The TIA is configured to obtain the first gain from the control apparatus, and after receiving the first signal, amplify the first signal by using the first gain.
