1. A method for receiving an analog signal, comprising:
in each time slot:
determining a first automatic gain factor of a control channel, wherein the control channel is Physical Sidelink Control Channel (PSCCH);
receiving, according to the first automatic gain factor, a first analog signal of the control channel sent by user equipment that transmits the control channel;
determining whether the user equipment that transmits the control channel and user equipment that transmits a traffic channel are the same user equipment, wherein the traffic channel is Physical Sidelink Discovery Channel (PSDCH), and the control channel and the traffic channel are time-division multiplexed;
in response to determining the same user equipment transmits the control channel and the traffic channel, determining whether a difference between a time-domain position of the control channel and a time-domain position of the traffic channel is less than a preset duration threshold;
in response to the difference being less than the preset duration threshold, adopting the first automatic gain factor as a second automatic gain factor of the traffic channel; and
in response to the difference being not less than the preset duration threshold, determining the second automatic gain factor of the traffic channel;
in response to determining different user equipment transmits the control channel and the traffic channel, determining the second automatic gain factor of the traffic channel; and
receiving, according to the second automatic gain factor, a second analog signal of the traffic channel sent by the user equipment that transmits the traffic channel;
wherein determining whether user equipment that transmits the control channel and user equipment that transmits the traffic channel are the same user equipment comprises:
determining whether a first pilot symbol of the control channel and a second pilot symbol of the traffic channel satisfy pre-configured pilot symbols corresponding to the same user equipment.
