Abstract:This paper presents a new cooperative spectrum sensing scheme, which allocates two separate short periods for sensing and cooperation to achieve high capability of detecting the Primary User (PU) with low interference. A mathematical model is built to derive a closed formulation of the detection probability of the CR users for guiding a real system design. Extensive simulations results demonstrate that the proposed method is superior to non-cooperative sensing and relay-based method [3] in terms of high sensin… Show more
