Time variation of the magnitude and phase of multipath delay in practical indoor radio channels

Presents the time variation in both the magnitude and phase of multipath delay in a typical office with transmission and receiving antennas fixed. Statistical analysis of the time variation is also presented. The authors carried out two different kinds of measurements. One was under typical conditions; that is, in a typical office, where several tens of people move as usual, with transmission and receiving antennas fixed. In the other, a couple of people intentionally walked across the line-of-sight (LOS) between antennas to estimate the maximal shadowing effect in ordinary cases.<>
