This work characterizes the interference distribution of a Cognitive Radio ad hoc Network (CRAHN) based on Code Division Multiple Access (CDMA). The authors start to explore an analytical model for the multiple-access interference of a Primary User (PU), being thereafter extended to embrace the co-existence of a Secondary User (SU) network. Several scenarios are simulated and the results are compared to the proposed analytical model. %G English %Z TC 5 %Z WG 5.5 %2 https://inria.hal.science/hal-01365764/document %2 https://inria.hal.science/hal-01365764/file/978-3-642-28255-3_54_Chapter.pdf %L hal-01365764 %U https://inria.hal.science/hal-01365764 %~ IFIP %~ IFIP-AICT %~ IFIP-TC %~ IFIP-TC5 %~ IFIP-WG %~ IFIP-WG5-5 %~ IFIP-DOCEIS %~ IFIP-AICT-372
