ABSTRACT
An overwhelming number of models in the literature
use average interference for calculation of capacity of a
CDMA network. In this paper, we calculate the actual per-
user interference and analyze the effect of user-distribution
on the capacity of a CDMA network. We show that even
though the capacity obtained using average interference
is a good approximation to the capacity calculated using
actual interference for a uniform user distribution, the
deviation can be tremendously large for non-uniform user
distributions.
Keywords: Inter-cell interference, Capacity, CDMA,
User distribution.
