In this article, the analysis, design, and development of a 37-GHz asymmetric Doherty power amplifier (DPA) are presented. practical DPA, main (PA) shows nonideal characteristic, which varies effect load modulation. Based on theoretical we derive relationship among efficiency, back-off (PBO) level, corresponding impedance in The result suggests that Class-AB PA decreased PBO efficiency during To achieve good compromise between level PA, modulation scheme is redesigned work. A 2-dB chosen to...
Recommender systems (RS) play a critical role in delivering personalized content across various online platforms, leveraging collaborative filtering (CF) as key technique to generate recommendations based on users' historical interaction data. Recent advancements CF have been driven by the adoption of Graph Neural Networks (GNNs), which model user-item interactions bipartite graphs, enabling capture high-order signals. Despite their success, GNN-based methods face significant challenges due...
