21. Estimation and detection of transmission line characteristics in the copper access network
Sammanfattning : The copper access-network operators face the challenge of developing and maintaining cost-effective digital subscriber line (DSL) services that are competitive to other broadband access technologies. The way forward is dictated by the demand of ever increasing data rates on the twisted-pair copper lines. LÄS MER
22. Optimal Transmit Strategies for Multi-antenna Systems with Joint Sum and Per-antenna Power Constraints
Sammanfattning : Nowadays, wireless communications have become an essential part of our daily life. During the last decade, both the number of users and their demands for wireless data have tremendously increased. Multi-antenna communication is a promising solution to meet this ever-growing traffic demands. LÄS MER
23. Channel Estimation and Prediction for 5G Applications
Sammanfattning : Accurate channel state information (CSI) is important for many candidate techniques of future wireless communication systems. However, acquiring CSI can sometimes be difficult, especially if the user equipment is mobile in which case the future channel realisations must be estimated/predicted. LÄS MER
24. Downlink Resource Allocation in Cooperative Wireless Networks
Sammanfattning : 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.

25. Studies on the role of NGF in arthritis-induced pain transmission using gait and weight bearing as outcome measures
Sammanfattning : Pain is one of the most common reasons for seeking healthcare, with approximately forty percent of those suffering from chronic pain having joint pain. Osteoarthritis is the most common cause of joint pain, but currently there are few treatments available. LÄS MER
