1. Energy-Efficient Fixed-Coefficient FIR Filters for Millimeter-Wave Radios
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknikSammanfattning : With the introduction of millimeter-wave antenna arrays in 5G base-stations and ever-increasing data volumes, the power consumption of the signal processing in digital radio systems has increased over the last decade. This, combined with increased cost and environmental awareness, has put focus on power optimization. LÄS MER
2. Embedded digital filter design and implementation
Master-uppsats, Uppsala universitet/Institutionen för informationsteknologiSammanfattning : Digital filters have been widely used in signal processing, to reduce or remove unwanted signals of different types, such as noise, and interference, and to enhance or keep desired signals. They are implemented as algorithms on an embedded system (a microcontroller) or a computer. LÄS MER
3. Development of an embedded system platform for signal analysis and processing
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och systemSammanfattning : Information is often stored and transmitted through electrical signals. This information may need refinement, which may be done by processing and altering the electrical signals, in which it is transmitted. When refining a signal, a frequency selective filter is often used. It can be implemented through digital signal processing (DSP). LÄS MER
4. IP block signalbehandling
Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Institutionen för elektroteknikSammanfattning : The thesis aims to implement different digital filters such as finite impulse response (FIR), infinite impulse response (IIR) and cascade integrator comb (CIC) on the field-programmable gate array (FPGA) development board using hardware description language (VHDL). To this purpose, Intel’s systems integration tool Platform designer is used to convert the implementation to an IP core. LÄS MER
5. Adder Minimization and Retiming in Parallel FIR-Filters : Targeting Power Consumption in ASICs
Master-uppsats, Linköpings universitet/DatorteknikSammanfattning : Parallelized implementations of FIR-filters are often used to meet throughput and power requirements. The most common methods to optimize coefficient multiplication in FIR-filters are developed for single rate filters, thus the added redundancy of parallel implementations cannot be utilized in the optimization.
