1. On Performance Analysis of Retransmission Schemes with Fading Channels
Abstract : 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. READ MORE

3. Adaptive Concatenated Coding for Wireless Real-Time Communications
Abstract : 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.

4. HARQ Systems: Resource Allocation, Feedback Error Protection, and Bits-to-Symbol Mappings
Abstract : Reliability of data transmission is a fundamental problem in wireless communications. Fading in wireless channels causes the signal strength to vary at the receiver and this results in loss of data packets. To improve the reliability, automatic repeat request (ARQ) schemes were introduced. READ MORE
