On the performance of interference cancellation in wireless ad hoc networks
Pages 433 - 437
Abstract
This letter presents a novel approach for deriving a lower bound on the outage probability of interference cancellation receiver in ad hoc networks for a class of channel fading. Our approach is based on the following observation: under the power decay law model for large-scale fading with an exponent α strictly greater than 2, the sum of the interferences at a receiver has the same order as the strongest signal. This feature still holds when the small-scale fading has a finite 2/α-fractional moment. This fact is used to develop an approximation which is also a compact lower bound on the outage probability.
