    Author : Xinlei Yi; Karl H. Johansson; Dimos V. Dimarogonas; John S. Baras; Antonis Papachristodoulou; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Distributed nonconvex optimization; distributed online convex optimization; distributed event-triggered control; primal-dual algorithm; stochastic gradient descent; zeroth-order algorithm; Electrical Engineering; Elektro- och systemteknik;

    Abstract : In distributed optimization and control, each network node performs local computation based on its own information and information received from its neighbors through a communication network to achieve a global objective. Although many distributed optimization and control algorithms have been proposed, core theoretical problems with important practical relevance remain. READ MORE

  2. 2. Distributed Optimization with Nonconvexities and Limited Communication

    Author : Sindri Magnússon; Carlo Fischione; Juan Miguel Morales González; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distributed Optimization; Resource Allocation; Power Networks; Limited Communication; Nonconvex Optimization; Wireless Sensor Networks; Cyberphysical Systems.; Electrical Engineering; Elektro- och systemteknik;

    Abstract : In economical and sustainable operation of cyber-physical systems, a number of entities need to often cooperate over a communication network to solve optimization problems. A challenging aspect in the design of robust distributed solution algorithms to these optimization problems is that as technology advances and the networks grow larger, the communication bandwidth used to coordinate the solution is limited.

  3. 3. Optimization and Fundamental Insights in Full-Duplex Cellular Networks

    Author : Jose Mairton B. da Silva Jr.; Carlo Fischione; Gabor Fodor; Geoffrey Ye Li; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; full-duplex; optimization; power control; assignment; beamforming; millimeter wave; self-interference; multi-antenna; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The next generations of cellular networks are expected to provide explosive data rate transmissions and very low latencies. To meet such demands, one of the promising wireless transmissions candidates is in-band full-duplex communications, which enable wireless devices to simultaneously transmit and receive on the same frequency channel.

  4. 4. Spatial Resource Allocation in Massive MIMO Communications : From Cellular to Cell-Free

    Author : Trinh Van Chien; Emil Björnson; Erik G. Larsson; David Gesbert; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Massive MIMO (multiple-input multiple-output) is considered as an heir of the multi-user MIMO technology and it has gained lots of attention from both academia and industry since the last decade. By equipping base stations (BSs) with hundreds of antennas in a compact array or a distributed manner, this new technology can provide very large multiplexing gains by serving many users on the same time-frequency resources and thereby bring significant improvements in spectral efficiency (SE) and energy efficiency (EE) over the current wireless networks.
