Reconfigurable intelligent surfaces (RISs) represent a promising candidate for sixth-generation (6G) wireless networks, as the RIS technology provides new solution to control propagation channel in order improve efficiency of link through enhancing received signal power.

In this paper, we explore the integration of two revolutionary technologies, reconfigurable intelligent surfaces (RISs) and orthogonal time frequency space (OTFS) modulation, to enhance high-speed wireless communications. We introduce a novel phase shift design algorithm for RIS-assisted OTFS, optimizing energy reception channel gain in dynamic environments. The study evaluates proposed approach downlink scenario, demonstrating significant performance improvements compared benchmark schemes...
In this paper, we propose a novel transmission scheme, called <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">sparse layered MIMO</i> (SL-MIMO), that combines non-orthogonal and singular value decomposition (SVD) precoding. Non-orthogonality in SL-MIMO allows re-using of the eigen-channels which improves spectral efficiency error rate performance system through enhancing coding gain diversity gain. We also present low-complexity...
