摘要
超宽带(Ultra Wide Band,UWB)技术是一种无线载波通信技术,它不采用正弦载波,而是利用纳秒级的非正弦波窄脉冲传输数据,因此其所占的频谱范围很宽。UWB技术具有系统复杂度低,发射信号功率谱密度低,对信道衰落不敏感,截获能力低,定位精度高等优点,尤其适用于室内等密集多径场所的高速无线接入。本课题主要研究UWB技术在矿井人员、车辆定位系统中的应用。
Ultra Wide Band(UWB)technology is a wireless carrier communication technology that does not use sinusoidal carriers,but uses nanosecond non sinusoidal narrow pulses to transmit data,thus occupying a wide spectrum range.UWB technology has the advantages of low system complexity,low power spectral density of transmitted signals,insensitivity to channel fading,low interception ability,and high positioning accuracy.It is particularly suitable for high-speed wireless access in dense multipath environments such as indoor environments.This project mainly studies the application of UWB technology in mine personnel and vehicle positioning systems.
