Robust Power Control with Distribution Uncertainty in Cognitive Radio Networks
IEEE Journal on Selected Areas in Communications
In cognitive radio networks, it is often impossible to have regular information exchange between PUs and SUs. This implies that SUs are unable to obtain up-to-date channel information at the PU side, and will face technical challenges in accurately controlling their interference to PUs through power control. In this paper, we assume that SUs can estimate the channel information in the reciprocal channel, and study the channel uncertainty due to estimation errors and its impact on SUs'doi:10.1109/jsac.2013.131125 fatcat:psytfygl5zhf7mn33j2bhtoylu
