Reducing Power Consumption of Digital Predistortion for RF Power Amplifiers Using Real-Time Model Switching
IEEE Transactions on Microwave Theory and Techniques(2022)
摘要
In this article, we propose a new behavioral modeling method to reduce the running complexity and power consumption of digital predistortion (DPD) models for radio frequency power amplifiers. By employing the proposed method, different cross terms in a DPD model can be switched dynamically in real time. Each cross-term branch can further choose the model coefficients from multiple coefficient sets...
