With increasing spatial reuse of the radio spectrum,
co-channel interference is becoming the dominant noise source
and may severely degrade the communication performance of
wireless transceivers. In this paper, we consider the problem of
statistical-physical modeling of co-channel interference from an
annulus field of Poisson interferers. Our contributions include (1)
demonstrating the applicability of the symmetric alpha stable
and Middleton Class A distributions in modeling co-channel
interference in various topologies of interferers, and (2) deriving
analytical conditions on the system parameters for which these
distributions accurately model the statistical properties of the
interference. Through simulation, we compare the decay rate of
tail probabilities of the empirical co-channel interference and
the symmetric alpha stable, Middleton Class A, and Gaussian models
for different topologies of interferers. Practical applications
include co-channel interference modeling for various wireless
network environments, including ad-hoc and cellular networks.
