Pseudo-random Pulse Sequences Aided UWB-TR Communication System
Ultra-Wideband (UWB) Transmitted Reference (TR) scheme has been recently applied in many wireless location applications to achieve data communication due to its low complexity. Its major drawback is serious performance degradation for a very noisy template. In this paper, a novel pseudo-random (PN) pulse sequences aided UWB-TR communication system is presented by replacing the traditional repetitive reference pulses with multiple short PN sequences reference pulses. 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 UWB-TR system is described and its performance in a multipath channel is analyzed and simulated. The result shows that it has a better bit-error-ratio performance than that of an averaged TR system.
