  1. 1. Multiantenna Cellular Communications Channel Estimation, Feedback, and Resource Allocation

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Emil Björnson; KTH.; KTH.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; channel estimation; limited feedback; multicell communications; resource allocation;

    Abstract : The use of multiple antennas at base stations and user devices is a key component in the design of cellular communication systems that can meet the capacity demands of tomorrow. The downlink transmission from base stations to users is particularly limiting, both from a theoretical and a practical perspective, since user devices should be simple and power-efficient, and because many applications primarily create downlink traffic (e.
