1. On Bit-Wise Decoders for Coded Modulation
Abstract : Coded modulation is a technique that emerged as a response to the growing demand for high data rates. It was devised to achieve high spectral efficiency with high reliability, potentially approaching Shannon’s capacity. The main idea of coded modulation consists in combining error-correcting coding with higher-order modulation. READ MORE

2. Bit-Wise Decoders for Coded Modulation and Broadcast Coded Slotted ALOHA
Abstract : This thesis deals with two aspects of wireless communications. The first aspect is about efficient point-to-point data transmission. To achieve high spectral efficiency, coded modulation, which is a concatenation of higher order modulation with error correction coding, is used. READ MORE

3. Towards Accurate Estimation of Error Sensitivity in Computer Systems
Abstract : Fault injection is an increasingly important method for assessing, measuringand observing the system-level impact of hardware and software faults in computer systems. This thesis presents the results of a series of experimental studies in which fault injection was used to investigate the impact of bit-flip errors on program execution. READ MORE

4. On the Quality of Delivery for Variable Bit Rate Video
Abstract : Several factors affect the perceived quality of a video streamed over a network. Technical aspects related to the codec and the video play an important role besides the delivery of the video content in a timely and error-free manner. READ MORE

5. In-Line Bit Interleaved Serially Concatenated Coded Modulation
Abstract : A communication system using in-line bit interleaved serially concatenated trellis coded modulation (SCTCM) over the additive white Gaussian noise (AWGN) channel is investigated. In-line bit interleaving refers to an interleaving method for which the random bit interleaver is divided into several independent constituent bit interleavers. READ MORE
