Impact of the Secondary Network on the Outage Performance of the Primary Service in Spectrum Sharing

In this paper, we utilize stochastic geometry to analyze the primary service outage performance for spectrum sharing in Rayleigh fading environment. Using this approach, the impacts of the secondary service parameters as well as the wireless environment on the primary service outage probability are analyzed. We further obtain a closed form for the primary service outage probability based on the transmit power of the secondary service as well as miss detection probability of the spectrum sensing. Furthermore, we obtain the maximum secondary service transmitter node density for a given outage probability constraint of the primary service. We also derived an upper bound to the achievable capacity of the primary service. Simulations results confirm the analytical derivations.
