Time Reversal for Ultra-wideband (UWB) Sensor Networking

Abstract

This report organized into six chapters. It addresses coupling effects, an analysis of the virtual array, single-user and multi-user time reversal UWB-MIMO system performance, and a comparison with time reversal UWB-MISO. The central topic of this report is to experimentally study the multiusers MIMO with time reversal transmission. When transmitting to 10 users simultaneously in the system, it is found that the interference is high and BER performance is poor, thus, MIMO multiple access schemes such as zero-forcing at the transmitter must be considered.
