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.

Signal processing method and signal processing apparatus

A method and a device for generating simulation data, a computer device and a storage medium are provided. The method includes: receiving user input through a user interface, where the user input includes a data type parameter, a value parameter, a generation time parameter and a target interface parameter of data to be generated; searching for a pre-stored data template file corresponding to the data type parameter; generating a data packet queue based on the value parameter by using the data template file; and sending each data packet in the data packet queue to a target interface corresponding to the target interface parameter based on a sending moment specified by the generation time parameter. With this method, the cost of the test system can be reduced and the flexibility of available test data can be improved.
