Title : Achievable Transmission Capacity of Secondary System in Cognitive Radio Networks

Conference : IEEE ICC 2010 
Abstract : This paper evaluates the secondary system’s transmission capacity in cognitive ratio networks, defined by the maximum spatial density of successful transmissions while guaranteeing the outage probability constraints of the secondary and the primary systems. By using stochastic geometry, the relation between the spatial densities, the transmission powers, and the transmission capacities of spectrum sharing systems are presented. Subsequently, the optimal spatial density of the secondary system and the optimal transmission power ratio of the primary system to the secondary system are derived. Furthermore, the achievable transmission capacity is defined using the derived optimal values. From the theoretical results, it is shown that the optimal transmission power ratio is affected by not the density of the primary system, but the system parameters including the target outage probability. In addition, the achievable transmission capacity of the secondary system decreases as the spatial density of the primary system increases
at the decreasing rate determined by the system parameters of the primary system.
