Title
UWB MISO Time Reversal With Energy Detector Receiver Over ISI Channels
Abstract
This paper investigates a multiple input single output (MISO) time reversal system for ultra-wideband (UWB) communication over inter-symbol interference (ISI) channels. Time reversal takes advantage of rich scattering environments to achieve signal focusing, which enables the use of simple receiver structures without sacrificing performance. On-off-keying (OO K) modulation and energy detection (square law) are considered for the purpose of low complexity at the receiver. This research is motivated by the need for high-data-rate wireless network with simple receive nodes. The discrete channel models and bit error rate (BER) formulas for the energy-detector receiver over ISI channels are derived. Performance is evaluated based on measured data, considering practical signal waveforms. One reason to use our own measured data is that there is no proper UWB channel model for antenna array related study. Numerical results suggest that the proposed MISO time reversal system with extremely simple receiver is promising to support high data rate in severe multipath environments for robust communication in the UWB band.
