Abstract

The performance of a digital wireless network that operates in a Rayleigh fading environment in the presence of Gaussian noise and heavy-tailed impulsive interference that can be modelled by an α -stable process is investigated. Such wireless networks include ad hoc or cognitive radio networks that operate in an unbounded fading/shadowing environment with a Poisson interference field. For the system under consideration, a novel closed-form expression for the average bit error probability of digital modulation schemes, valid for any arbitrary real values of the characteristic exponent, α , is derived. The validity of the proposed formulation is attested through Monte Carlo simulation results.
