Abstract: Based on the research of nonlinear amplification characteristics of power amplifiers, a reconfigurable predistortion linearization method for short-wave power amplifiers on a hardware platform with a SoC as the core is proposed in this paper. The paper focuses on improving the augmented Hammerstein model. The modified model is not only easy to be implemented on hardware, but also has a mode switching function, which can be selected as a memory model or a memory-less model according to application requirements. The experiment results illustrate that the modified model can effectively suppress the out-of-band spurious radiation of the short-wave power amplifier. The predistortion linearization scheme based on SoC hardware platform proposed in this paper can be easily applied to implement various predistortion nonlinear models. It can economize the hardware resources for the system and has important practical engineering application value.
