A new formula for the angle-of-arrival probability density function in mobile environment

This paper theoretically derives an angle-of-arrival (AoA) probability density function in multi-path mobile environment where the scatterer distribution obeys a hyperbolic sech function. Using simulations, comparisons are made between the Gaussian distribution and the hyperbolic sech distribution for different distance from the base station (BS), user equipment (UE) and UE's effective radius.
