Original Abstract

This contribution provides experimental evidence for the two-wave with diffuse power (TWDP) fading model. Wehave conducted two indoor millimetre wave measurement campaigns with directive horn antennas at both link ends.One horn antenna is mounted in a corner of our laboratory, while the other is steerable and scans azimuth andelevation. Our first measurement campaign is based on scalar network analysis with 7 GHz of bandwidth. Our secondmeasurement campaign obtains magnitude and phase information; it is additionally sampled directionally at severalpositions in space. We apply Akaike’s information criterion to decide whether Rician fading sufficiently explains thedata or the generalised TWDP fading model is necessary. Our results indicate that the TWDP fading hypothesis isfavoured over Rician fading in situations where the steerable antenna is pointing towards reflecting objects or isslightly misaligned at line-of-sight. We demonstrate TWDP fading in several different domains, namely, frequency,space, and time.
