This paper focuses at the investigation of the degree of orthogonality of\nchannels of multiple users in densely populated indoor and outdoor scenarios.\nFor this purpose, a statistical millimeter wave (mmwave) MIMO channel simulator\nis carefully designed using state of the art channel models. At the mmwave\nfrequencies, human/vehicular mobility around the mobile users may partially or\ncompletely block the communication link. This give rise to the consideration of\nnew channel modeling parameter i.e. probability of a user to be in LOS\ndynamics. Higher line of sight (LOS) probabilities may increase the spatial\ncorrelation among the multiuser channels. Therefore, quantification of the\nspatial separation of users in different scenarios with distinct LOS\nprobabilities is crucial and it is the subject of investigation of this paper.\nAdditionally, the mutual orthogonality of channels by changing the number of\nbase station (BS) antennas and inter antenna element distance (IED) have also\nbeen investigated. Analysis shows that LOS blockage of certain scenario has\nmore impact at the degree of orthogonality among users as compared to the\nnumber of BS antennas and the spacing between the antenna elements.\n
