Abstract

In this paper, we examine some channel characteristics of SISO and MIMO systems based on the measured channel data in our measurement campaigns. We confirm that due to the mutual coupling between antennas, patterns of antenna elements are changed and different from an omnidirectional one of a single antenna. Results also show that received power, channel auto-correlation, and Doppler spectrum are much dependent not only on the direction of the RX motion, but also on the array orientation. In the NLOS environment, observed Doppler spectrum is quite different from the theoretical U-shaped Jakespsila one.
