摘要

测量了室内无线电信道的时间变化。时间变化是由人的运动或人引起的通信设备在其他静态室内无线电信道上的运动引起的。在报告的窄带测量中，观察到最大多普勒扩频为6.1 Hz，最大RMS多普勒带宽为0.87 Hz。测量结果表明，当信号包络变化小于10 dB时，瑞利包络衰落是一个很差的假设。

Fading Results From Narrowband Measurements Of The Indoor Radio Channel

Temporal variations of the indoor radio channel are measured. Temporal variations are caused by human movement or human induced motion of the communication equipment on the otherwise static indoor radio channel. For the reported narrowband measurements, a maximum Doppler spread of 6.1 H z and a maximum RMS Doppler bandwidth of 0.87 Hz were observed. The measurements revealed that Rayleigh envelope fading is a poor assumption when the signal envelope variations are less than 10 dB.
