Time-Reversal Based Range Extension Technique for Ultra-wideband (UWB) Sensors and Applications in Tactical Communications and Networking

Abstract

The focus of this report is on major improvement and system test. Receiver sensitivity has been significantly improved and about 3 dB time reversal precoding gain has been observed based on system trial in indoor non-line-of-sight scenario. Theoretical study shows that additional gain can be achieved by using optimum waveform design. Listed below are major achievements during the quarter: 1. multiple integration window sizes; 2. comprehensive system test; 3. improved receiver sensitivity to -81 dBm; 4. 3 to 4 dB time reversal precoding gain in indoor non-line-of-sight scenario. We will continue to improve the system and conduct more measurements, while seeking some technology transfer opportunities.
