Summary:The invention provides a power amplifier linearization method and device, and belongs to the technical field of communication. The power amplifier linearization method comprises the following steps: identifying a power amplifier according to input data and output data of the power amplifier to obtain the model and distortion information of the power amplifier, and calculating the ACLR of the input data of the power amplifier; performing parameter initialization configuration on a model of the power amplifier according to the model and distortion information of the power amplifier and the ACLR to obtain parameters in an initial state; and performing multiplication operation on the parameters and an output signal of the power amplifier to obtain a linear output characteristic parameter of the power amplifier, performing root mean square error (NMSE) calculation on the linear output characteristic parameter of the power amplifier and an input signal of the power amplifier, and adjusting a parameter of a model of
