2. Optimization, Matroids and Error-Correcting Codes
Abstract : The first subject we investigate in this thesis deals with optimization problems on graphs. The edges are given costs defined by the values of independent exponential random variables. We show how to calculate some or all moments of the distributions of the costs of some optimization problems on graphs. READ MORE

3. Error-Correcting Codes Based on Chaotic Dynamical Systems
Abstract : This dissertation treats a novel class of error-correcting codes based on chaotic dynamical systems. The codes are defined over a continuous alphabet whereas the information that is to be transmitted belongs to a discrete set of symbols. Simple expressions can be given for the encoders, and the codewords can be described by a parity-check relation. READ MORE

4. Capabilities of Convolutional Codes: Unequal Error Protection and More
Abstract : Many communication systems obtain enhanced performance by using concatenated coding schemes. Turbo codes and woven convolutional codes are two examples of such schemes. READ MORE

5. Analysis and Design of Spatially-Coupled Codes with Application to Fiber-Optical Communications
Abstract : The theme of this thesis is the analysis and design of error-correcting codes that are suitable for high-speed fiber-optical communication systems. In particular, we consider two code classes. The codes in the first class are protograph-based low-density parity-check (LDPC) codes which are decoded using iterative soft-decision decoding. READ MORE
