  • METHOD FOR COMPENSATING FOR NONLINEAR DISTORTION OF SIGNAL, MODEL, AND COMMUNICATION SYSTEM
    Publication number: 20250343717
    Abstract: A method for compensating for nonlinear distortion of a signal, a model, and a communication system are disclosed. Based on a preset nonlinear compensation fusion model, digital pre-distortion (DPD), crest factor reduction (CFR) and error compensation are separately performed on an initial orthogonal frequency division multiplexing (OFDM) signal, and an initial OFDM signal after nonlinear distortion compensation is obtained accordingly. The nonlinear compensation fusion model may include a band limited-digital pre-distortion (BL-DPD) module, a band limited-crest factor reduction (BL-CFR) module and an error compensation module.
    Type: Application
