Abstract:

This final report summarizes major project activities and results achieved during last three years. This project has involved a great amount of theoretical and development work. The primary goal is to demonstrate an SNR gain without using multiple antennas, so that transmission range can be increased. This goal has been reached by using UWB time reversal on our real-time testbed. Propelled by the project, our overall research has harvested in a number of aspects. The first UWB time reversal system with real-time waveform precoding at the transmitter was demonstrated in our lab in year 2009. The original time reversal technique has been generalized by transmitting an optimization based waveform, considering implementation limitations. Tremendous experience in real-time system design and implementation has been gained throughout the development cycle.
