On the capacity of multi-user cognitive radio networks
Amin Jafarian, Sriram Vishwanath · 2009
This paper studies the K > 2 user cognitive radio network. In this paper, there are one licensed transmit-receive pair and K - 1 cognitive transmit-receive pairs wishing to communicate simultaneously. For the case of a class of ¿very strong¿ interference channels, this paper shows that all users can simultaneously communicate as if all cross-channels in the interference network were absent.
