超宽带脉冲无线传输

Discussion on ultra-wideband pulse wireless transmission

超宽带无线技术包括基带脉冲传输方式和带通载波调制传输方式两大类。脉冲传输是把信息调制在离散脉冲信号上发射,带通载波调制传输是把信息调制在正弦载波上发射。超宽带无线系统主要采用基带脉冲传输技术,具有高空间频谱效率、高测距精度、低功耗、低成本、小体积等诸多优点和潜力。

The wireless technology on UWB（Ultra-Wideband） include 2 transmission types of baseband pulse and bandpass carrier wave modulation, The pulse transmission modulates signals on divergence pulse. The bandpass carrier wave modulates signals on sine wave. UWB wireless system adopts technology of baseband pulse trans- mission. The technology has advantages and latent capacity of high space spectrum effect： high precision of measuring distance, low power consumption, low cost and small volume.
