Joint Spectrum, Precoding, and Phase Shifts Design For RIS Aided by ylp65 is a document available to read on EtoBox.
This paper presents a novel approach for optimizing precoding, phase shifts, and adaptive sub-band bandwidth (ASB) allocation in RIS-aided multiuser MIMO THz systems using a metapath-based heterogeneous graph-transformer network (MHGphormer). The MHGphormer bypasses the challenging channel estimation phase and achieves higher system sum-rate compared to existing methods, while accommodating varying user numbers and improving spectral efficiency. Simulation results demonstrate significant performance gains i
