Abstract
This application discloses example multi-phase-based Doherty power amplifier control methods and apparatus. An example method includes obtaining a baseband signal and generating two vector signals based on the baseband signal, where the two vector signals each include a phase signal and amplitude signal, and the two vector signals are non-orthogonal signals. Amplitude control signals of a target power amplifier are obtained based on quantization encoding of amplitude signals of the two vector signals, where the target power amplifier includes a main and power amplifier, and the main and auxiliary power amplifier each include a plurality of working cells. Phase control signals of the target power amplifier are obtained based on phase signals of the two vector signals. Based on the phase control signals and the amplitude control signals, a plurality of working cells in the main power amplifier and the auxiliary power amplifier to output power signals are controlled.
