Abstract: A communication device includes: one or more voltage conversion circuits. The one or more voltage conversion circuits are separately coupled to a power supply of the communication device. A voltage sampling circuit is coupled to the power supply, and/or the voltage sampling circuit is coupled to an output end of at least one of the one or more voltage conversion circuits. A controller is configured to: control the voltage sampling circuit to collect voltages output by the power supply or voltages output by a first voltage conversion circuit in a plurality of sending timeslots or a plurality of receiving timeslots of the communication device; and determine a real voltage of the power supply based on the voltages output by the power supply or the voltages output by the first voltage conversion circuit in the plurality of sending timeslots or the plurality of receiving timeslots of the communication device.
