Analysis of Antenna-to-Antenna Spatial Correlation in Multi-User Millimeter-Wave Systems

Abstract

this paper investigates the antenna-to-antenna spatial correlation of a multi-consumer millimeter-wave (mm Wave) system, considering the angular spread of every randomly located antenna inside the mobile. A signal-power-dependent correlation model based on the azimuth perspective domain is proposed. Furthermore, an iterative clustering set of rules for unmarried-cellular beam forming is advanced and analyzed to quantify the performance of multi-user mm Wave structures. Simulation outcomes show that after the angular spread exceeds 20°, the antenna-to-antenna correlation must be considered within the analysis. The beam forming overall performance with antenna correlation substantially progresses with a reduction in the number of antennas, and the benefit increases because the angular spread increases.
