This application provides an antenna calibration apparatus and an antenna calibration method. The antenna calibration apparatus includes: l antennas; l antenna filters, where first ends of the l antenna filters are respectively connected to the l antennas; l radio frequency links, respectively connected to second ends of the l antenna filters; and a calibration circuit, connected to each of the second ends of the l antenna filters, and configured to: send or receive a first calibration signal through a position between each antenna filter in the l antenna filters and a radio frequency link connected to the second end of each antenna filter; and calibrate each antenna based on the first calibration signal.

Antenna calibration apparatus and antenna calibration method

The present disclosure discloses a method for compensating a measured environmental parameter. The method may include obtaining one or more sets of conditions associated with a heat generating device including an electric power value of the heat generating device. The method may further include, for each set of the one or more sets of conditions, obtaining a plurality of groups of measured data acquired by a first sensing device, and a plurality of groups of reference data, which are both associated with an environmental parameter corresponding to a power-on duration of the heat generating device. The method may further include determining, for each group of the plurality of groups of measured data and reference data, a deviation of the environmental parameter associated with the first sensing device between the measured data and the reference data, and determining a relationship between the deviation and the power-on duration of the heat generating device.

Environmental parameter measurement systems

In an antitheft method for a mobile terminal that relates to the field of communications technologies, a baseband processor detects integrity of an operating system running on an application processor, generates a short message service (SMS) message when the operating system has no integrity, and transfers the SMS message to the application processor. The application processor controls a display to display the SMS message in order to inform a user that the operating system of the mobile terminal is damaged. In a scenario in which a mobile terminal is stolen and an operating system is maliciously tampered with, according to the solution provided in this application, an SMS message is used to prompt a user, thereby improving security of the mobile terminal.

Antitheft method for mobile terminal and apparatus

The present disclosure discloses a method for compensating environmental measurement data. The method may include obtaining a relationship among a deviation of a measured value of an environmental parameter of a first sensing device, an electric power value of a heat generating device, and a power-on duration of a heat generating device, the first sensing device deployed near the heat generating device; obtaining a current electric power value of the heat generating device, a current power-on duration of the heat generating device, and a current measured value of the environmental parameter; determining a current deviation based at least in part on the current electric power value of the heat generating device, the current power-on duration of the heat generating device, and the relationship; and determining a corrected measured value of the environmental parameter based on the current measured value of the environmental parameter and the current deviation.
