Novel Relax-and-Retract Algorithm for Intelligent Reflecting Surface Design
نویسندگان
چکیده
In this paper, a novel relax-and-retract algorithm is proposed to tackle the nonconvex unit-modulus constraint in joint intelligent reflecting surface (IRS) and multiuser multiple-input multiple-output (MU-MIMO) transceiver design. The conventional method semidefinite relaxation (SDR), its computational complexity large. By using symbol detection mean square error (MSE) as quality of service (QoS), approach enables us get convex quadratically constrained quadratic programming (QCQP) subproblems, which have much lower than SDR approach. Simulation results show that has excellent performance terms complexity, while transmit power hardware implementation are same those

Performance Analysis of cooperative SWIPT System: Intelligent Reflecting Surface versus Decode-and-Forward
In this paper, we explore the impacts of utilizing intelligent reflecting surfaces (IRS) in a power-splitting based simultaneous wireless information and power transfer (PS-SWIPT) system and compare its performance with the traditional decode and forward relaying system. To analyze a more practical system, it is also assumed that the receiving nodes are subject to decoding cost, and they are on...

متن کاملReflecting on Backward Design for Knowledge Translation; Comment on “A Call for a Backward Design to Knowledge Translation”
In a recent Editorial for this journal, El-Jardali and Fadlallah proposed a new framework for Knowledge Translation (KT) in healthcare. Many such frameworks already exist; thus, new entrants to the field must be scrutinized in regard to their unique contributions to advancing understanding and practice. The El-Jardali and Fadlallah framework focuses on policy-level discussions, a relatively und...

متن کاملReal-time intelligent pattern recognition algorithm for surface EMG signals
BACKGROUND Electromyography (EMG) is the study of muscle function through the inquiry of electrical signals that the muscles emanate. EMG signals collected from the surface of the skin (Surface Electromyogram: sEMG) can be used in different applications such as recognizing musculoskeletal neural based patterns intercepted for hand prosthesis movements. Current systems designed for controlling t...
