1. Aspects on Interference and Diversity in Wireless Networks
Abstract : This thesis deals with two topics in wireless communications: interference between frequency-hopping (FH) networks, and multiuser diversity. The work on FH treats a system where FH is used to provide simultaneous access to the channel for multiple uncoordinated wireless networks. READ MORE

2. Multiuser diversity orthogonal frequency division multiple access systems
Abstract : Multiuser diversity can be used to significantly increase system throughput in wireless communication systems. The idea is to schedule users when they experience good channel conditions and let them wait when the channels are weak. In this thesis, several aspects on multiuser diversity OFDMA systems are investigated. READ MORE

3. Scheduling in multiservice wireless networks
Abstract : Wireless access networks that support services such as voice, video telephony, email and web-surfing are being deployed world-wide today. The bit rates for these networks are in most cases lower than the bit rates of wireline broadband access networks. READ MORE

4. Resource Allocation under Uncertainty : Applications in Mobile Communications
Abstract : This thesis is concerned with scheduling the use of resources, or allocating resources, so as to meet future demands for the entities produced by the resources. We consider applications in mobile communications such as scheduling users' transmissions so that the amount of transmitted information is maximized, and scenarios in the manufacturing industry where the task is to distribute work among production units so as to minimize the number of missed orders.

5. Practical Deployment Aspects of Cell-Free Massive MIMO Networks
Abstract : The ever-growing demand of wireless traffic poses a challenge for current cellular networks. Each new generation must find new ways to boost the network capacity and spectral efficiency (SE) per device. A pillar of 5G is massive multiple-input-multiple-output (MIMO) technology. READ MORE
