Abstract -- In this contribution a temporally corre-
lated rayleigh fading channel model applicable in gen-
eral scattering environments, with Clarke's isotropic
scattering environment as a special case, is consid-
ered. For a fixed direction of mobile travel, the results
show that the information rate penalty incurred for
not knowing the channel state information (CSI) in
a non-isotropic scattering environment can be signifi-
cantly less than that for the isotropic scattering envi-
ronment for the same average received signal-to-noise
power ratio (SNR). The results show that for a fixed
mean angle of arrival, fading rate and direction of
