1. On Bit-Wise Decoders for Coded Modulation
Abstract : Coded modulation is a technique that emerged as a response to the growing demand for high data rates. It was devised to achieve high spectral efficiency with high reliability, potentially approaching Shannon’s capacity. The main idea of coded modulation consists in combining error-correcting coding with higher-order modulation. READ MORE

2. On the Design of Turbo Codes
Abstract : This thesis is about Turbo codes - codes constructed via parallel concatenation of two recursive convolutional encoders linked by an interleaver. The focus of the work is on the understanding and design of Turbo codes. READ MORE

3. Towards Fully Optimized BICM Transmissions
Abstract : Bit-interleaved coded modulation (BICM) was introduced in 1992 as a new coded modulation (CM) scheme particularly well suited for fading channels and is nowadays considered the de facto CM scheme in wireless standards (HSPA, IEEE 802.11a/g/n, DVB-T2/S2/C2, etc.). 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. Custom Datapaths for DSP ASICs Methodology and Implementation
Abstract : This thesis regards datapath design and analysis at several abstraction levels. Five papers are presented that focus on datapath design for mobile communication systems and design methodologies for such datapaths. Paper I discusses different aspects of Turbo channel decoder design for high speed and low power applications. READ MORE
