Summary:
In this paper the propagation characteristics of a millimeter wave communication system are measured and analyzed in an indoor environment where a beam-tracking antenna seeks the incoming signal path electronically among signal paths?line-of-sight (LoS) or reflected wave paths?and then switches to the better SNR path so that the communication link could continue. The measurement results show much smaller delay spread with higher gain receiver antenna which then leads to simple and low power portable terminal implementation. Furthermore, depending on the physical positioning of the transmitter and receiver, there is a probability to have two rays received at the same or very close time that results in significant bit-error-rate degradation.
