Abstract: [slo] [eng]
Táto práca sa zaoberá možnosťami využitia koncepcie softwarového rádia pre rádioamatérske účely v pásme KV a jej následnej implementácie do vhodne navrhnutého hardwaru. Cieľom je návrh transceiveru schopného pracovať v režimoch AM, FM, SSB, a CW. V rámci teoretického rozboru problematiky sú preskúmané používané architektúry softwarových rádií a ich jednotlivé bloky. Rozbor je zameraný hlavne na analógové časti reťazca, ako sú vstupný a koncový zosilňovač, filtre a prevodníky. Ďalej sú preskúmané algoritmy spracovania signálov pre prijímač aj vysielač v daných režimoch a zostavené ich počítačové modely. Navrhnuté algoritmy sú následne implementované do obvodu FPGA (Virtex-5) na dostupnej vývojovej doske. This project deals with possibilities of using the software defined radio conception for radio amateur use in a short wave band and its subsequent implementation into properly designed hardware. The aim of this work is to design a transceiver that would be capable of working in AM, FM, SSB, and CW modes. Within a theoretical part of the project the architectures of software defined radios and their components are discussed. This part was focused mainly on analog parts of the chain, such as amplifiers, filters and converters. Signal processing algorithms for both receiver and transmitter working in desired modes are studied subsequently and their computer models are built. Designed algorithms are implemented into FPGA structure (Virtex -5).
