Abstract

Abstract

In high data rate Transmitted-Reference (TR) Ultra-WideBand (UWB) systems, the conventional autocorrelation receivers introduce the second-order Inter-Symbol Interference (ISI). This paper demonstrates that, through multiple antennas receive and Equal Gain Combining (EGC) significant diversity gain can be obtained. Furthermore, the multiple antennas combination can eliminate the BER floor with the alleviation of the model nonlinearities. The combined system can be simplified to a linear ISI model and the complexity of channel modeling and equalizer can be reduced greatly via a data-aided adaptive algorithm. The performance gap between the approximate linear model and the nonlinear model diminishes with increasing antennas.
