1. Coordinated Transmission for Wireless Interference Networks
Sammanfattning : 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. LÄS MER
2. Interference alignment and power control for wireless interference networks
Sammanfattning : 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.

3. Interference Alignment with Imperfect Channel Knowledge and Secrecy Constraints
Sammanfattning : 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. LÄS MER
4. Coordinated Precoding for Multicell MIMO Networks
Sammanfattning : Enabling multiple base stations to utilize the spatial dimension in a coordinated manner has been shown to be a fruitful technique for improving the spectral efficiency in wireless interference networks. This thesis considers multicell systems where base stations and mobile stations are equipped with multiple antennas. LÄS MER
5. Assembly of microsystems for optical and fluidic applications
Sammanfattning : This thesis addresses assembly issues encountered in optical and fluidic microsystem applications. In optics, the first subject concerns the active alignment of components in optical fibersystems. LÄS MER
