Abstract:This paper aims at giving some results on the performances of opportunistic spectrum access when taking into account sensing errors: non detection, which is the cause of collisions with a transmitting user, and false alarm, which is a cause of missed opportunity to access the channel. We give the probability An(i, j) of having i collisions and j successful access to the channel within n time slots when the primary user's activity can be described by a two-state On/Off model. Our derivation allows us to take in… Show more
