本文描述了宽带850 MHz数字无线电信号由于在一个大型建筑物内的多径传播而引起的时延扩展的测量。这些测量结果显示,中值RMS时间延迟扩展为125 ns,最差情况为250 ns。因此,高于400 kHz的信令速率可能不可行。
Measurements of time delay spread of wideband 850 MHz digital radio signals due to multipath propagation within a large building are described. These measurements show a median RMS time delay spread of 125 ns and a worst case of 250 ns. Consequently, signalling rates above 400 kHz may not be feasible.
