1. Trellis Source Coding Methods for Low Rates and Short Blocks
Abstract : Trellis quantization is a finite state machine based method for data compression. It is mainly applied to quantizing noise-like sources. In this thesis new trellis codes suitable for low rate quantization are derived. READ MORE

2. Source and Channel Coding for Audiovisual Communication Systems
Abstract : Topics in source and channel coding for audiovisual communication systems are studied. The goal of source coding is to represent a source with the lowest possible rate to achieve a particular distortion, or with the lowest possible distortion at a given rate. Channel coding adds redundancy to quantized source information to recover channel errors. READ MORE

3. On Secure and Sequential Source Coding
Abstract : Secure source coding is an important research area in recent years as it deals with the problem of transmitting sensitive information over insecure channels while protecting it from unauthorized access. This is particularly relevant in the context of modern communication systems where the data transmitted is often sensitive in nature and the threat of eavesdropping or data breaches is high.

4. Towards flexible audio coding
Abstract : thesis is about audio coding and improving flexibility thereof. Audio coding is used to reduce the bit rate needed to represent audio signals in digital format. When the available bit rate is low, parametric coding methods that use models to describe perceptually-important features of audio signals have shown their efficiency. READ MORE

5. Empirical Coordination over Networks Subject to Fidelity Criteria
Abstract : Communication is one of the most important and expensive resources in a network with different parts who desire to establish coordinated behavior. When the actions of some parts are distributed according to a probability distribution which is given by the nature of the problem, finding the minimum communication requirements to coordinate the actions of some other parts according to an empirical distribution can be posed as a network information theory problem.
