    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.

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; backhaul latency; Coordinated multi-point CoMP transmission; imperfect synchronization; fractional frequency reuse; resource allocation; general duality theory; imperfect channel state information; inter-cluster interference coordination;

    Abstract : The raised user expectations of quality of service and the rapid growth of the data traffics impose a great challenge for mobile communication systems. The performance, e.g., the spectrum efficiency, peak data rate, cell-edge data rate, of current cellular systems ismainly limited due to the presence of inter-cell interference. READ MORE
