Analysis and optimization of pilot-aided adaptive coded modulation under noisy channel state information and antenna diversity
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:157, Doctoral thesis, 2006)The thesis is largely built on a collection of published and submitted papers where the main focus is to analyze and optimize single-carrier adaptive coded modulation systems with and without antenna diversity. Multidimensional ... -
Emergent behavior based implements for distributed network management
(Dr.ingeniøravhandling, 0809-103X; 0806-103X, Doctoral thesis, 2003)Network and system management has always been of concern for telecommunication and computer system operators. The need for standardization was recognised already 20 years ago, hence several standards for network management ... -
Encrypted Computation
(Dr.ingeniøravhandling, 0809-103X; 2001:67, Doctoral thesis, 2001)The ability to construct software, call it a functional ciphertext, which can be remotely executed in encrypted form as an entirely self-contained unit, has the potential for some interesting applications. One such application ... -
Optimal Bit and Power Constrained Filter Banks
(Dr. ingeniøravhandling, 0809-103X; 2000:7, Doctoral thesis, 2000)In this dissertation, two filter banks optimization problems are studied. The first problem is the optimization of filter banks used in a subband coder under a bit constraint. In the second problem, a multiple input multiple ... -
Perforated Panel Absorbers with Viscous Energy Dissipation Enhanced by Orifice Design
(Dr. ingeniøravhandling, 0809-103X; 2000:67, Doctoral thesis, 2000)Currently, there is a great interest in panel absorber design where porous components are excluded due to environmental and cleaning considerations. For such absorbers, the challenge is to increase the natural, viscous ... -
Practical Thermal and Electrical Parameter Extraction Methods for Modelling HBT´s and their Applications in Power Amplifiers
(Dr. ingeniøravhandling, 0809-103X; 2003:20, Doctoral thesis, 2003)A new practical technique for estimating the junction temperature and the thermal resistance of an HBT was developed. The technique estimates an interval for the junction temperature. The main assumption in the new technique ... -
Quality of service differentiation, teletraffic analysis and network layer packet redundancy in optical packet switched networks
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:122, Doctoral thesis, 2005)Optical Packet Switching (OPS) has emerged as a promising candidate for the next-generation Wavelength Division Multiplexed (WDM) based alloptical network. By enabling packet switching in the optical domain, OPS networks ... -
Quality of Service, Traffic Conditioning and Resource Management in Universal Mobile Telecommunication System (UMTS)
(Dr. ingeniøravhandling, 0809-103X; 2003:6, Doctoral thesis, 2003)The successful deployment of Universal Mobile Telecommunication System (UMTS) is heavily dependent on Quality of Service (QoS) to be achieved. This thesis addresses a few facets of the QoS issues in UMTS, including traffic ... -
Real-Time Phase Ambiguity Resolution in Global Navigation Satellite Systems
(Dr. ingeniøravhandling, 0809-103X; 2001:104, Doctoral thesis, 2002)This dissertation focuses on real-time carrier phase ambiguity resolution for high precision solutions in Global Navigation Satellite Systems (GNSS). In order to exploit the full accuracy potential, one must be able to ... -
Three-Dimensional Radio Channel Modeling for Mobile Communications Systems
(Dr. ingeniøravhandling, 0809-103X; 2001:89, Doctoral thesis, 2001)The work described in this report is within the area of three-dimensional (3D) radio channel modeling for mobile communications. The focus was towards rural areas, because radio coverage of rural areas is more costly when ... -
Towards Plug-and-Play Services: Design and Validation Using Roles
(Dr. ingeniøravhandling, 0809-103X; 2003:47, Doctoral thesis, 2003)Today telecommunication service users expect to access a similar set of services independently of what network they happen to use, they expect services to adapt to new surroundings and contexts as they move around, and ...
