Abstract :
Wireless LANs increasingly experience interference from other users operating in the same frequency band. In this paper, the aim is to develop techniques to learn from the interference environment in order to find the best strategy for radio transmissions. An analytical model is proposed to characterize the radio environment around a particular node. A compensated estimator is derived for the activity of nodes. Simulations show that the proposed estimators are reasonably accurate, particularly for high capture thresholds.
