Abstract-- In this paper, we derive an upper-bound for
the pair-wise error probability of spac e-tim e c odes whic h
c aptures the effec ts of the transm itter and the rec eiver
antenna c onfi g urations (antenna separation and antenna
g eom etry ) and the surrounding sc attering distributions at
the transm itter and the rec eiver antenna array s. T his
new upper-bound allows investig ation of the individual
effec ts of antenna c onfi g uration and sc attering environm ent
param eters on the perform anc e of spac e-tim e c odes. U sing
this upper-bound, we q uantify the deg ree of the effec t of
antenna c onfi g uration on the diversity advantag e g iven by
a spac e-tim e c ode. S im ulation results show that as the
num ber of antennas inc rease within a fi x ed aperture, the
diversity advantag e of a spac e-tim e c ode is upper-lim ited
by the siz e of the antenna aperture.
