Abstract
Different from the statistical or bound method to build the interference model of cognitive wireless networks, in this paper, we propose an exact mathematical interference model based on the primary channel and the secondary interference channel under Rayleigh and Nakagami fading respectively. Under the rigorous mathematical derivation, the proposed model can cover many parameters such as spatial distribution, the spectrum sensing schemes, the transmission and channel propagation characteristics of nodes, etc. In addition, the analysis result can be extent to a number of applications including spatial density settlement of ST nodes, ST power control, spectrum sensing schemes analysis, irregular geographical shape evaluation of cognitive radio etc. The simulation results have verified our analytical model.
