Time Reversed Ultra-Wideband (UWB) Multiple-Input Multiple-Output (MIMO) Based on Measured Spatial Channels

Free registration required

Executive Summary

UWB technology is envisioned for future wireless high data rate transmission. A UWB system with multiple antennas takes advantage of the rich scattering environment to increase the data rate. On the other hand, given rich multipath, Time Reversal (TR) uses scatters to create space and time focalization at a target point by coherent addition of all scattered contributions at that point. This paper analyzes the performance of an impulse TR-MIMO-UWB system with a simple one-correlator receiver. The performance analyses are based on UWB spatial channels measured in an office environment.
