2. 1. Distributed Signal Processing in Digital Substations : Integrating High Sampling Rate Measurements at the Process-Level

   Author : Fabian Hohn; Lars Nordström; Peter Crossley; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Communication networks; digital signal processing; digital substation; field-programmable gate array; filter design; IEC 61850; IEC 61869; power system protection; substation automation; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Future power systems will be dominated by power electronic (PE) converter connected generation. This trend is primarily driven by the increasing penetration of wind power as well as the increasing integration of photovoltaic (PV) based generation. READ MORE

4. 2. Custom Datapaths for DSP ASICs Methodology and Implementation

   Author : Pontus Åström; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik; handshake circuits; design patterns; design abstraction; design methodology; UMTS; interleaver architecture; Turbo decoder implementation; low power; Digital filter; wave digital filter;

   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

5. 3. Studies on Design and Implementation of Low-Complexity Digital Filters

   Author : Henrik Ohlsson; Lars Wanhammar; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low-complexity digital filters; lattice wave digital filters LWDFs ; digital down converter DDC ; analog-to-digital converters ADCs ; Signal processing; Signalbehandling;

   Abstract : In this thesis we discuss design and implementation of low-complexity digital filters. Digital filters are key components in most digital signal processing (DSP) systems and are, for example, used for interpolation and decimation. READ MORE

6. 4. On mapping of digital filter algorithms to hardware

   Author : Oscar Gustafsson; Ulf Sjöström; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : In this thesis we discuss various issues involving the design path for low power design of frequency-selective digital filters. As recursive filters have a bound on the minimal iteration period, Tmin we focus on these. Implementations that obtain Tmin are known as maximally fast. READ MORE

7. 5. Om implementation of maximally fast wave digital filters

   Author : Mark Vesterbacka; Markuu Renfors; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : An approach to design and implement fixed-function digital filters using bit-serial arithmetic is proposed. The resulting implementations are maximally fast, i.e., the maximal sample frequency fmax is equal to the upper bound on the sample frequency given by the recursive parts of the algorithm. READ MORE
