11. MIMO Decoding Algorithm and Implementation
Abstract : Multi-Input Multi-Output system has been one of the hot technologies for future wireless communications, since it can increase the capacity (coverage or link quality in other senses) at no cost in frequency spectrum. This doctoral thesis investigates improvements to MIMO decoding algorithms and presents VLSI implementation results. READ MORE

12. Fair Scheduling and Resource Allocation in Packet Based Radio Access Networks
Abstract : Wireless communication systems are by nature and by regulations limited in bandwidth and are therefore limited in capacity. Services with Quality of Service (QoS) requirements will enforce a more efficient utilisation of the available capacity. READ MORE

13. Trellis Decoding: From Algorithm to Flexible Architectures
Abstract : Trellis decoding is a popular method to recover encoded information corrupted during transmission over a noisy channel. Prominent members of this class of decoding algorithms are the Viterbi algorithm, which provides maximum likelihood estimates, and the BCJR algorithm, which is a maximum a posteriori estimator commonly used in iterative decoding.

14. Overload control strategies for distributed communication networks
Abstract : In distributed communication networks several nodes interact to carry out services. New telecommunication networks support a variety of services, much different from traditional telephony. Each service has its own so called load profile, which means that the amount of capacity needed to complete a service varies. READ MORE

15. Fairness in Communication and Computer Network Design
Abstract : In communication networks, fair sharing of resources is an important issue for one main reason. The growth of network capacity is in general not matching the rapid growth of traffic. Consequently, the resources consumed by each user have to be limited. This implies that users cannot always be assigned the end-to-end bandwidth they ask for. READ MORE
