| 摘 要： | 介绍了我国煤炭开采中数据通信的现状和UWB的发展,阐明了脉冲产生方法及工作原理.详细分析了UWB抗多径、低功耗、强穿透力和高集成化等特点.结合煤矿井下的实际情况,提出了超宽带是一种适合煤矿井下且具有很大发展前景的无线通信技术.比估计的自适应变速方法.该方法根据估计流星信道信噪比的变化情况,动态地改变系统的比特速率,实现自适应变速,从而有效提高了流星信道利用率,实现数据的可靠传输.仿真结果表明,在相同信道条件下,该系统的数据通过量比固定速率传输系统提高2～4 倍,是一种有效而可靠的通信方法.

| Abstract: | The data communication actuality and the development of ultra wideband (UWB) in Chinese coal mine exploitation were introduced, and the producing UWB pulse method was expatiated. The UWB characteristics of the multi path resister, low power, strong penetrating power and highly integration were analyzed detaily. Based on the real condition of the coal mine underground,the UWB was advanced that it is a better wireless communication way adopted in the coal mine underground and has a extensively development future. |
