6. Error-Correcting Codes Based on Chaotic Dynamical Systems
Sammanfattning : 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. LÄS MER
7. Practical Anytime Codes
Sammanfattning : The demand of an increasingly networked world is well reflected in modern industrial control systems where communication between the different components of the system is more and more taking place over a network. With an increasing number of components communicating and with hardware devices of low complexity, the communication resources available per communication link are however very limited. LÄS MER
8. Quantum error correction
Sammanfattning : Quantum error correction is the art of protecting quantum states from the detrimental influence from the environment. To master this art, one must understand how the system interacts with the environment and gives rise to a full set of quantum phenomena, many of which have no correspondence in classical information theory.

9. An Encounter with Convolutional Codes over Rings
Sammanfattning : Convolutional codes is one possibility when there is a need for error-correcting codes in communication systems. Using convolutional codes over rings is a relatively new approach. LÄS MER
10. Tales of Tailbiting Codes
Sammanfattning : Tailbiting codes are error correcting codes and can be used in digital transmission systems. They are obtained by terminating convolutional codes into block codes. This thesis consists of an introduction to convolutional and tailbiting codes, and the Papers A--G that include the main results. LÄS MER
