Abstract: A signal processing apparatus includes a power amplifier and a power supply modulator. The signal processing apparatus obtains a first non-linear coefficient, where the first non-linear coefficient indicates a non-linear characteristic of the power amplifier and a non-linear characteristic of the power supply modulator. The signal processing apparatus performs non-linear preprocessing and correction on a first baseband signal based on the first non-linear coefficient, to obtain a first intermediate signal and a second intermediate signal. The signal processing apparatus performs digital-to-analog conversion on the first intermediate signal and then performs up-conversion processing, to obtain a third intermediate signal. The signal processing apparatus performs envelope processing on the second intermediate signal, to obtain a first envelope signal. The signal processing apparatus modulates the first envelope signal by using the power supply modulator, to obtain a first control voltage signal.

Abstract: A first device sends first information to a second device, where the first information includes at least one of an identifier of the first device, position information of the first device, configuration information of the first device, or a time point at which the first device obtains second information, where the second information includes artificial intelligence information and/or sensing information. The second device determines indication information based on the first information and sends the indication information to the first device, where the indication information indicates a type and/or a format of information to be transmitted by the first device. The first device determines third information based on the indication information, where the third information is the second information or a part of the second information, or is determined based on the second information. The first device sends the third information to the second device.
