Performance of UWB MIMO relay systems in real UWB channels

In this paper, the performance of various ultra-wideband (UWB) multiple-input multiple-output (MIMO) relay systems is evaluated for the first time based on UWB channel measurements. In particular, the measurement results for UWB relay channels in line-of-sight as well as non-line-of-sight indoor environments are presented. The average bit error rates of dual-hop MIMO relay systems and cooperative MIMO relay systems are examined and compared in the measured channels.
