Abstract
A joint temporal and spatial sensing based cooperative communication scheme is proposed, in which the cognitive users including source and relays share the spectrum with licensed (primary) user. The closed form expression of outage probability is obtained for the proposed scheme in Rayleigh fading environment. The outage probability of our proposed transmission scheme has been compared with schemes with pure temporal and pure spatial sensing.
