Spatial-polarizational correlation-coefficient function between receiving-antennas in radiowave communications - geometrically modeled, analytically derived, simple, closed-form, explicit formulas

This paper analytically derives closed-form expressions of the uplink received-signal's polarization-parameterized spatial-correlation-coefficient functions across the basestation antenna-array's spatial aperture, based on a geometrical model of idealized spatial relationships among the transmitter, the scatterers, and the receiving antennas. The derived formulas fit well with some empirical data.
