  1. 6. Channel Prediction Based On Sinusoidal Modeling

    Författare :Ming Chen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Long range channel prediction is considered as one of the most important enabling technologies to future wireless communication systems. The prediction of Rayleigh fading channels is studied in the frame of sinusoidal modeling in this thesis. A stochastic sinusoidal model to represent Rayleigh fading channel is proposed. LÄS MER

  3. 7. On Pose Estimation in Room-Scaled Environments

    Författare :Hanna E. Nyqvist; Gustaf Hendeby; Fredrk Gustafsson; Isaac Skog; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Pose (position and orientation) tracking in room-scaled environments is an enabling technique for many applications. Today, virtual reality (vr) and augmented reality (ar) are two examples of such applications, receiving high interest both from the public and the research community. LÄS MER

  4. 8. Convex Optimization for Assignment and Generalized Linear Regression Problems

    Författare :Efthymios Tsakonas; Björn Ottersten; Ami Wiesel; KTH; []
    Nyckelord :;

    Sammanfattning : This thesis considers optimization techniques with applications in assignment and generalized linear regression problems. The first part of the thesis investigates the worst-case robust counterparts of combinatorial optimization problems with least squares (LS) cost functions, where the uncertainty lies on the linear transformation of the design variables.

  5. 9. Channel Estimation Aspects of Reconfigurable Intelligent Surfaces

    Författare :Doga Gürgünoglu; Gabor Fodor; Emil Björnson; Jaap van de Beek; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reconfigurable intelligent surface; channel estimation; pilot contamination; positioning; angle of arrival estimation; integrated sensing and communications; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : In the sixth generation of wireless communication systems (6G), there exist multiple candidate enabling technologies that help the wireless network satisfy the ever-increasing demand for speed, coverage, reliability, and mobility. Among these technologies, reconfigurable intelligent surfaces (RISs) extend the coverage of a wireless network into dead zones, increase capacity, and facilitate integrated sensing and communications tasks by consuming very low power, thus contributing to energy efficiency as well.
