Abstract- This paper presents an analytical model for the
fading channel correlation in general scattering environments.
In contrast to the existing correlation models, our new approach
treats the scattering environment as non-separable and it is
modeled using a bi-angular power distribution. The bi-angular
power distribution is parameterized by the mean departure
and arrival angles, angular spreads of the univariate angular
power distributions at the transmitter and receiver apertures,
and a third parameter, the covariance between transmit and
receive angles which captures the statistical interdependency
between angular power distributions at the transmitter and
receiver apertures. When this third parameter is zero, this new
model reduces to the well known "Kronecker" model. Using
the proposed model, we show that Kronecker model is a good
