1. Aperiodic Array Synthesis for Telecommunications
Sammanfattning : Arrays of antennas offer important advantages over single-element antennas and are thus a key part of most advanced communication systems. The majority of current arrays are based on a classical regular layout, which offer simple design criteria despite some limitations. LÄS MER
2. The impacts of network effects and multi-service provision on consumer switching costs in the Swedish telecommunications market
Sammanfattning : The Swedish telecommunications market has been liberalised since 1990s. Liberalisation gave an opportunity to several new entrants to enter to the market. Consumers also gained benefits from more telecom providers and services to choose from, and lower telecom prices. LÄS MER
3. A flexible framework for detection of feature interactions in telecommunication systems
Sammanfattning : The complexity of today's telecommunications systems grows with each new feature introduced. As the number of services an operator provides can be used to gain advantage over competitors the number of services will continue to increase. LÄS MER
4. Applications of Soft Computing Techniques for Wireless Communications
Sammanfattning : This thesis presents methods and applications of Fuzzy Logic and Rough Sets in the domain of Telecommunications at both the network and physical layers. Specifically, the use of a new class of functions, the truncated π functions, for classifying IP traffic by matching datagram size histograms is explored. LÄS MER
5. Human perception in speech processing
Sammanfattning : The emergence of heterogeneous networks and the rapid increase of Voice over IP (VoIP) applications provide important opportunities for the telecommunications market. These opportunities come at the price of increased complexity in the monitoring of the quality of service (QoS) and the need for adaptation of transmission systems to the changing environmental conditions.
