1. Hybrid ARQ Using Serially Concatenated Block Codes for Real-Time Communication : An Iterative Decoding Approach
Sammanfattning : The ongoing wireless communication evolution offers improvements for industrial applications where traditional wireline solutions causes prohibitive problems in terms of cost and feasibility. Many of these new wireless applications are packet oriented and time-critical. LÄS MER
2. On Performance Analysis of Retransmission Schemes with Fading Channels
Sammanfattning : Future wireless communication systems and services bring increased performance demands, with respect to data-rate(s), reliable communication, (stochastic) real-time guarantees, and more. In this context, not only new communication schemes are needed, but also more capable performance analysis methods are essential. LÄS MER
3. Improved Techniques for Retransmission and Relaying in Wireless Systems
Sammanfattning : The last three decades have seen significant advances in the wireless communication field. As the data rates of wireless systems are increasing, the demand for mobile services also is increasing rapidly. Like other natural resources, radio spectrum suitable for mobile wireless communications is also limited. LÄS MER

5. Adaptive Concatenated Coding for Wireless Real-Time Communications
Sammanfattning : The objective of this thesis is to improve the performance of real-time communication overa wireless channel, by means of specifically tailored channel coding. The deadlinedependent coding (DDC) communication protocol presented here lets the timeliness and thereliability of the delivered information constitute quality of service (QoS) parametersrequested by the application.
