ABSTRACT:
This thesis presents the design of a receiver / transmitter chain used in the BushLAN system. The BushLAN project aims to provide broadband internet access to remote areas in Australia where no land-line is available.
The system is designed to operate in the TV spectrum between 45 MHz and 820MHz with a bandwidth of up to 4 MHz and 4Mbit/s at an output power of 5 W. Based on an image rejection mixer chip, a superheterodyne system consisting of mixers, amplifiers and switches is designed.
Theoretical results for phase noise impact on the bit error rate are presented and conclusions based on measurements from the system are drawn.
BIO:
Lukas Kull studied Electrical Engineering and Information Technology at
the Swiss Federal Institute of Technology in Zurich (ETHZ), Switzerland.
He focussed on telecommunication systems and analogue hardware design and was involved in projects based on dualband antennas at the Institute for Electromagnetic Fields and Microwave Electronics at ETHZ and on a recently patented infrared antenna sensor at the IBM Research Laboratories.
He spent the last 6 months on his Master's project at ANU on exchange which is the last part towards his Msc degree at ETHZ in Switzerland.
