Deep Reinforcement Learning for RIS-Assisted FD Systems: Single or Distributed RIS?
نویسندگان
چکیده
This paper investigates reconfigurable intelligent surface (RIS)-assisted full-duplex multiple-input single-output wireless system, where the beamforming and RIS phase shifts are optimized to maximize sum-rate for both single distributed deployment schemes. The preference of using or scheme is investigated through three practical scenarios based on links' quality. closed-form solution derived optimize vectors a novel deep reinforcement learning (DRL) algorithm proposed shifts. Simulation results illustrate that choice depends scenario It further shown significantly improves compared non-optimized in Besides, derivation achieves remarkable improvement approximated previous works. Finally, complexity analysis confirms DRL reduces computation literature.

to achieve a breakthrough in the World Trade Organization’s Doha Round. Their goal is to get an agreement by the end of 2008. Developing countries should pull the plug on this moribund round until rich countries can agree to a new framework that lives up to Doha’s promise to be a “Development Round” that favours poorer countries. As rich country leaders try to rally negotiators for yet another ...
متن کاملAriadne (Ris¿ report)
This is a report on an attempt to develop a CSCW infrastructure that can support the construction and use of malleable and linkable coordination mechanisms. On the basis of a scenario derived from field studies, the paper outlines the Ariadne framework, describes the notation’s main features and illustrates how it can be applied to the scenario. The paper attempts to bridge from sociological in...
متن کاملRIS or PACS: Who is in the Driver’s Seat?
Diagnostic reports. A radiologist at a PACS workstation needs ready access to prior reports. In most situations, reports are initially pushed to the RIS by the SR application, usually via an HL7 interface. If prior reports are stored in the RIS, how can they be available when a radiologist needs to look at them, for example, when reviewing a follow-up exam? T Most RIS systems cannot be queried ...
