  3. 3. Downlink Resource Allocation in Cooperative Wireless Networks

    University dissertation from Stockholm : KTH

    Author : Jingya Li; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; precoding design; load balancing; relaying; imperfect channel state information; imperfect synchronization; Coordinated multi-point transmission; I Q imbalance; resource allocation; fractional frequency reuse;

    Abstract : Wireless cooperative networks, which is based on exploiting coordination among multiple access nodes, has been considered as a promising approach to improve the spectral efficiency, reduce the energy consumption, and extend the network coverage of future wireless communication systems. In practice, the actual benefit of multi-node cooperation is affected by a variety of factors, including the quality of channel state information (CSI), the constraints on the feedback and backhaul links, hardware impairments, resource allocation and data processing schemes.
