1. Compensating for Unreliable Communication Links in Networked Control Systems
Sammanfattning : Control systems utilizing wireless sensor and actuator networks can be severely affectedby the properties of the communication links. Radio fading and interferencemay cause communication losses and outages in situations when the radio environmentis noisy and low transmission power is desirable. LÄS MER
2. Development and evaluation of methods for control and modelling of multiple-input multiple-output systems
Sammanfattning : In control, a common type of system is the multiple-input multiple-output (MIMO) system, where the same input may affect multiple outputs, or conversely, the same output is affected by multiple inputs. In this thesis two methods for controlling MIMO systems are examined, namely linear quadratic Gaussian (LQG) control and decentralized control, and some of the difficulties associated with them.

3. The Knowledgeable Parent : Ideologies of Communication in Swedish Health Discourse
Sammanfattning : This thesis explores the communication of health knowledge among new parents in Sweden. Based on three separate studies, the thesis employs a selection of theoretical concepts and methodological approaches, mainly originating from mediated discourse analysis and linguistic anthropology.

4. Cooperative Communications : Link Reliability and Power Efficiency
Sammanfattning : Demand for high data rates is increasing rapidly for the future wireless generations, due to the requirement ofubiquitous coverage for wireless broadband services. More base stations are needed to deliver these services, in order tocope with the increased capacity demand and inherent unreliable nature of wireless medium. LÄS MER
