Angle and time of arrival statistics for hollow-disc and elliptical scattering models

This paper derives explicit closed-form expressions for the joint/marginal probability density functions of the uplink/downlink multipathspsila time-of-arrival (TOA) and azimuth angle-of-arrival (AOA) in a wireless-communication fading channel. These models assume that the scatterers lie within a hollow-disc and an elliptical space, respectively. These probability density functions (pdf) provide insight into the properties of the spatial wireless channel.
