  1. 1. Study of Mutual Coupling in Finite Antenna Arrays for Massive MIMO Applications

    Författare :Tomislav Marinovic; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiple scattering; Massive MIMO; mutual coupling MC ; 5G; iterative methods; base station antenna BSA ;

    Sammanfattning : This thesis focuses on the study of mutual coupling (MC) in finite antenna arrays for base station antennas (BSAs) for Massive multiple-input multiple-output (MIMO) applications, with an emphasis on the development of a computationally-efficient modeling technique for the analysis of MC which can be readily applied in the design or synthesis schemes for BSAs. Traditionally, the effects of MC have been ignored or underestimated in the analyses performed within the information-theoretic-based communities by assuming idealized antenna elements with no MC between them or by considering the fictitious isotropic radiator models.

  3. 2. Sparse Array Architectures for Wireless Communication and Radar Applications

    Författare :Navid Amani; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; base station antenna BSA ; sparse array; grating lobe; multi-user MU MIMO; multipath channel; mutual coupling; direction-of-arrival DOA estimation; MIMO radar; 5G; network theory;

    Sammanfattning : This thesis focuses on sparse array architectures for the next generation of wireless communication, known as fifth-generation (5G), and automotive radar direction-of-arrival (DOA) estimation. For both applications, array spatial resolution plays a critical role to better distinguish multiple users/sources. LÄS MER
