1. Synchronization in Turbo Coded Systems
Abstract : Turbo codes and their unusual properties have attracted significant attentionof the information theory community. There already exist many articlesand papers devoted to the theory of these codes. This thesis, however,focuses on practical implementation issues of turbo codes, with synchronizationproblems as the main topic. READ MORE

2. Reduced Receivers for Faster-than-Nyquist Signaling and General Linear Channels
Abstract : Fast and reliable data transmission together with high bandwidth efficiency are important design aspects in a modern digital communication system. Many different approaches exist but in this thesis bandwidth efficiency is obtained by increasing the data transmission rate with the faster-than-Nyquist (FTN) framework while keeping a fixed power spectral density (PSD).

3. 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

4. Baseband Processing for 5G and Beyond: Algorithms, VLSI Architectures, and Co-design
Abstract : In recent years the number of connected devices and the demand for high data-rates have been significantly increased. This enormous growth is more pronounced by the introduction of the Internet of things (IoT) in which several devices are interconnected to exchange data for various applications like smart homes and smart cities.

5. Turbo Codes and Channel Estimation in Wireless Systems
Abstract : This thesis focuses on practical implementation issues of turbo codes with imperfectly estimated fading wireless channels and limited code length. Channel estimation can be divided into estimation of static parameters, such as constant timing and phase offset, and dynamic parameters, such as fading channel amplitudes. READ MORE
