Abstract: In this paper, based on 28 GHz MIMO channel measurements performed for both line-of-sight (LOS) and non-line-of-sight (NLOS) scenarios, channel characteristics and capacity are analyzed. Specifically, Ricean K factor, delay spread, angle spread of departure and arrival are summarized, channel capacity and antenna spatial correlation on multiple-input multiple-output (MIMO) capacity are investigated. Results show that K factor, root mean square (RMS) delay spread and angle spreads depend on measurement environment and scenario, cumulative distribution function (CDF) curve of delay spread in LOS case fits better with normal distribution comparing with in NLOS case. The larger spatial correlation corresponds to smaller MIMO channel capacity. The results can be used for design of 28 GHz MIMO radio systems.
