| Summary: | The ultra-wideband (UWB) technique is a promising technology in the current
wireless communication because it can be differentiated from other conventional
narrowband wireless technologies with the excess bandwidth (>500 MHz). One type
of UWB signal is impulse radio UWB (IR-UWB), which has the advantages of high
data rates and low power by transmitting very short duration pulses [1]. However,
there are several R&D challenges investigating the performance and developing
IR-UWB systems, including the tremendous time needed for conducting real-time
experiments and high cost involved with system development.
To solve this problem, the Advanced Design System (ADS), which is an advanced
software from Agilent Technologies used for a wide variety of designs and
simulations, can play a significant role in simulating the performance of indoor
IR-UWB systems. In this project, IR-UWB systems are constructed in ADS, and the
measurements ofthe real-time device are performed to characterise the simulations.
These simulation models are then incorporated into the ADS simulation environment
through custom made toolkits.
This project contributes to the design of the ADS custom toolkits for IR-UWB
systems. The toolkits include pulse generator, transmitter antenna, receiver antenna
and IR-UWB receiver which are designed and fabricated by previous year students.
The kits can be distributed and modified for users to explore the performance of
different IR-UWB system architectures.
