摘要

In this paper, a novel pseudo-noise (PN) sequence assisted noise suppression scheme for Ultra-Wideband (UWB) transmitted reference (TR) system is presented by replacing the repetitive reference pulses with multiple short PN reference pulse sequences. The receiver uses them to estimate the channel impulse response and based on this to form an improved template which removes the parts mainly consist of noise and gives the multipath components that have better signal-to-noise ratio higher weights. The proposed system is described and its performance in a multipath channel is analyzed and simulated. The result shows that the proposed system has a better bit-error-ratio performance than that of an averaged TR system.
