1. On Soft Decoding and Robust Vector Quantization
Sammanfattning : This thesis considers vector quantization for noisy channels. Vector quantization (VQ) is an important technique for block-based source coding, with applications in, e.g., speech and image coding. LÄS MER
2. Soft decoding vector quantization for noisy channels
Sammanfattning : .... LÄS MER
3. Coding and Transmission Strategies for Secrecy
Sammanfattning : In this thesis we consider several problems relating to information theoretic security. The wiretap channel is the simplest information theoretic setting which takes security into account, and in the first chapters of the thesis we design some practical coding schemes for this channel model. LÄS MER
4. Coding for the Wiretap Channel
Sammanfattning : We consider code design for Wyner’s wiretap channel. Optimal coding schemes for this channel require an overall code that is capacity achieving for the main channel, partitioned into smaller subcodes, all of which are capacity achieving for the wiretapper’s channel. LÄS MER
5. On error-robust source coding with image coding applications
Sammanfattning : This thesis treats the problem of source coding in situations where the encoded data is subject to errors. The typical scenario is a communication system, where source data such as speech or images should be transmitted from one point to another. A problem is that most communication systems introduce some sort of error in the transmission. LÄS MER
