2. 1. Coordinated Transmission for Wireless Interference Networks

   Author : Hamed Farhadi; Mikael Skoglund; David Gesbert; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Interference; Wireless Network; MIMO; Coordinated Transmission; Resource Allocation; Interference Alignment; Scheduling; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Wireless interference networks refer to communication systems in which multiple source–destination pairs share the same transmission medium, and each source’s transmission interferes with the reception at non-intended destinations. Optimizing the transmission of each source–destination pair is interrelated with that of the other pairs, and characterizing the performance limits of these networks is a challenging task. READ MORE

4. 2. Interference alignment and power control for wireless interference networks

   Author : Hamed Farhadi; Mikael Skoglund; Michail Matthaiou; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Interference alignment; power control; limited feedback; wireless communication; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Abstract : This thesis deals with the design of efficient transmission schemes forwireless interference networks, when certain channel state information(CSI) is available at the terminals.In wireless interference networks multiple source-destination pairsshare the same transmission medium for the communications.

5. 3. Interference Alignment with Imperfect Channel Knowledge and Secrecy Constraints

   Author : Zhao Wang; Mikael Skoglund; Ming Xiao; Sheng Yang; KTH; []
   Keywords : Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : In this thesis, the degrees of freedom (DOF) of wireless networks are studied with imperfect channel state information at transmitters (CSIT) and/or secrecy constraints. Different interference alignment schemes are proposed to establish the DOF lower bound for a variety of wireless networks. READ MORE
