Hårdvarubaserade SOQPSK-algoritmer : En VHDL-implementation av algoritmer för att modulera & demodulera SOQPSK-signaler
Description :
Beroende på i vilken miljö man har tänkt att använda trådlös kommunikation behöver man hitta en modulationsteknik som passar under rådande förhållanden. I början på 1980-talet utvecklade den Amerikanska militären en modulationsteknik som kallas för Shaped BPSK (SBPSK) avsedd att tillämpas i kommunik...

Prestandajämförelse mellan mjuk och hård FPGA-processorkärna A performance comparison between soft and hard FPGA CPU core
Author(s) :
Skoglund, Thomas
Description :
Examensarbetsuppgiften har gått ut på att genomföra en prestandajämförelse mellan en hård och en mjuk processorkärna integrerad i en FPGA, i detta fall, en Virtex4 FX12 från Xilinx. System med de olika kärnorna har tagits fram, där antalet klockcykler för att genomföra olika beräkningar har mäts. ...

Cosine Modulated Filter Banks Cosinus-modulerade filterbankar
Author(s) :
Nord, Magnus
Description :
The initial goal of this report was to implement and compare cosine modulated filter banks. Because of time limitations, focus shifted towards the implementation. Filter banks and multirate systems are important in a vast range of signal processing systems. When implementing a design, there are seve...

FPGA-baserad multisignalgenerering med adaptiv Crestfaktor FPGA based multi signal generation with adaptive Crest factor
Description :
Detta examensarbetet undersöker möjligheten att eliminera de amplitudtoppar som uppstår då flera sinussignaler av slumpmässiga frekvenser adderas. Det som eftersträvas är en signal innehållande flera godtyckliga frekvenser samtidigt som den bibehåller en låg Crestfaktor (eller PAPR). De metoder som ...

Utilizing FPGAs for data acquisition at high data rates
Author(s) :
Carlsson, Mats
Description :
The aim of this thesis was to configure an FPGA with high speed ports to capture data from a prototype 4 bit ΣΔ analogue-to-digital converter sending data at a rate of 2.4 Gbps in four channels and to develop a protocol for transferring the data to a PC for analysis. Data arriving in the four channe...

Interfacing an external Ethernet MAC/PHY to a MicroBlaze system on a Virtex-II FPGA Utveckling av ett graanssnitt mellan ett externt ethernetchip och ett Microblaze system på en Virtex-II FPGA
Author(s) :
Bernspång, Johan
Description :
Due to the development towards more dense programmable devices (FPGAs) it is today possible to fit a complete embedded system including microprocessor, bus architecture, memory, and custom peripherals onto one single reprogrammable chip, it is called a System-on-Chip (SoC). The custom peripherals ca...
