Abstract-- In this paper, we develop a MIMO channel model
for generating the channel gains between arbitrary arrays of
transmitter and receiver antennas, for a general class of non-line-
of-sight (NLOS) channels. The channel scattering environment is
defined by a double directional angular distribution describing
the power transferred from transmitter aperture to receiver
aperture in each direction. We propose several parametrized
bivariate distributions that are consistent with univariate scat-
terer distributions separately observed at the transmitter and
receiver. We derive the second order statistics of the channel
gains in terms of the double directional power distribution and
