α-stable multiple access interference modelling for amplify-and-forward multihop ad hoc networks

A multihop amplify-and-forward relaying network that considers multiple access interference is investigated. Owing to the ad hoc configuration, the interference distribution is not Gaussian. A symmetric α-stable model is proposed that adapts to the impulsive behaviour owing to its heavy tailed distribution. Based on the stability property, analytical work is developed for multihop interference modelling and the theoretical expressions of the error probability that depend on two parameters are then derived.
