OpenDPDv2 framework unifies NN-DPD learning and optimization for RF power amplifiers

Researchers have developed OpenDPDv2, an open-source framework designed to enhance digital predistortion (DPD) for radio frequency power amplifiers using neural networks. This framework integrates PA modeling, NN-DPD learning, and optimization for deployment. It features a novel TRes-DeltaGRU architecture that offers a lightweight temporal residual path for improved robustness and supports joint optimization with fixed-point quantization, leading to significant reductions in energy consumption for deployment-oriented applications.
