Capacity results for the multicast cognitive interference channel
Résumé
The capacity of the Multicast Cognitive Interference Channel (CIFC), where many primary users are interested in the same message, is investigated. In the light of the existing results on the CIFC, capacity is characterized for the very weak and very strong interference regimes as well as the mixed weak/strong interference scenario through novel inner and outer bounds. Moreover, the capacity regions of the corresponding Gaussian settings are likewise reported.
