Abstract

An ultra-high data rate Time Reversal (TR) Multiple-Input Multiple-Output (MIMO) Ultra-Wideband (UWB) communication system with space-time pre-equalizer is proposed. When the symbol duration is set to approach the duration of UWB monocycles, the data rate is close to the limit due to the extremely large bandwidth, resulting in the severe intersymbol interference (ISI). The zero-forcing (ZF)criterion based space-time pre-equalizer presented in this letter eliminates both ISI and multi-stream interference (MSI) caused by spatial multiplexing at the sampling time. With less demand for degree of freedom (the number of antenna) than other existing schemes, the proposed space-time pre-equalizer enables the data rate of TR-MIMO-UWB system to reach the order of Gbps without losing bit error rate (BER) performance.
