Performance Analysis on BER of IR-UWB under Maglev System

Abstract

Ultra-wideband (UWB) communication is a very competitive short-range wireless communication technology today. Among all UWB technologies, impulse radio-ultra wide band (IR-UWB) technology is widely used in the wireless communication signal transmission process in various railway transportation systems. This paper focuses on the rapid development of maglev transportation system in recent years, establishes a wireless transmission model of two most commonly used modulation technologies in IR-UWB communication, Pulse Amplitude Modulation (PAM) and Pulse Position Modulation (PPM), under electromagnetic environment of maglev system, and conducts a theoretical analysis of its Bit Error Rate (BER) performance. The conclusion points out that fully utilize the energy under the FCC power limit during signal transmission is the key to improve the BER performance of UWB system. Meanwhile, under the environment of high-speed maglev system, PAM’s bit error performance has a 3dB gain.
