GMP model improvement method and device, electronic equipment and storage medium

The invention provides a GMP model improvement method and device, electronic equipment and a storage medium, and relates to the technical field of communication, and the method comprises the steps: sampling a plurality of input signals and a plurality of output signals of a power amplifier at the current moment; based on the input signals, a GMP model library and a stability maintaining matrix are constructed, and the GMP model library comprises a plurality of polynomial libraries; the polynomial library comprises polynomials; the stability maintaining matrix is used for reducing the modulus value of the high-order polynomial; based on each polynomial library, determining a polynomial model matrix; the polynomial model matrix comprises a high-order term polynomial; determining parameters of a GMP model based on the polynomial model matrix, the dimensional stability matrix and each output signal; and based on the parameters of the GMP model, improving the GMP model to obtain an improved GMP model.
