1. On Tailbiting Codes from Convolutional Codes
Sammanfattning : Tailbiting is a method to terminate convolutional codes into block codes. We call these block codes tailbiting codes. This thesis focuses on the encoding of tailbiting codes. The tailbiting method is carefully investigated. LÄS MER
2. 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
3. Joint ML multi user detection of block coded CDMA over the AWGN channel using A*
Sammanfattning : .... LÄS MER
4. Voronoi-Based Coding
Sammanfattning : The performance of a digital communication system can generally be improved by increasing the number of variables being jointly coded. In this sense, it is desirable to have, e.g., higher-dimensional quantizers, longer channel codes, and more users in a multiple-access system. LÄS MER
5. On Probabilistic Shaping and Learned Decoders with Application to Fiber-Optic Communications
Sammanfattning : We live in an ubiquitously connected world whose backbone are optical fibers. Achieving high spectral efficiencies and hence high transmission rates requires a careful combination of forward error correction (FEC) and higher-order modulation. This is referred to as coded modulation. LÄS MER
