11. Reconfigurable Optical Interconnection Networks for High-Performance Embedded
Sammanfattning : In embedded computer and communication system the capacity demand for interconnection networks is increasing continuously in order to achieve high-performance systems. Recent breakthroughs show that by using reconfigurability inside a single chip substantial performance gains can be added. LÄS MER
12. Link Reliability in Cooperative Relaying Using Network Coding
Sammanfattning : Demand for high data rates is increasing rapidly for future wireless systems.This trend is due to the increase in the number of mobile subscribers that need bandwidth hungry multimedia applications anywhere, anytime. Fourth generation cellular systems like IMT-advanced are being developed to meet these requirements. LÄS MER
13. Coding for the Wiretap Channel
Sammanfattning : We consider code design for Wyner’s wiretap channel. Optimal coding schemes for this channel require an overall code that is capacity achieving for the main channel, partitioned into smaller subcodes, all of which are capacity achieving for the wiretapper’s channel. LÄS MER
14. On error-robust source coding with image coding applications
Sammanfattning : This thesis treats the problem of source coding in situations where the encoded data is subject to errors. The typical scenario is a communication system, where source data such as speech or images should be transmitted from one point to another. A problem is that most communication systems introduce some sort of error in the transmission. LÄS MER
15. Spectral Efficiency and Fairness Maximization in Full-Duplex Cellular Networks
Sammanfattning : Future cellular networks, the so-called 5G, are expected to provide explosive data volumes and data rates. To meet such a demand, the research communities are investigating new wireless transmission technologies. One of the most promising candidates is in-band full-duplex communications. LÄS MER
