To improve the robustness and reduce the energy consumption of non-orthogonal multiple access (NOMA) networks. based on hardware impairments (HWI) of transceiver and non-perfect channel state information (CSI). an intelligent reflecting surface (IRS) assisted transmission power minimization algorithm for NOMA networks was proposed. The joint optimization problem of active beam assignm... https://allfixelectricales.shop/product-category/griller-door-spring/
