Abstract -- We use a recently developed expression
for the bivariate Rayleigh cumulative distribution
function (CDF) to derive a novel analytical for-
mula for the average signal-to-noise ratio (SNR)
of the correlated dual selection combining (SC)
system under slow Rayleigh fading. We relate the
average SNR diversity gain to spatial correlation
as well as to antenna separation. Furthermore,
we also develop a more practical channel model in
which multipath scatters are from more than one
incident angle, each with a certain beamwidth.
