Coalitional Games in Partition Form for Joint Spectrum Sensing and Access in Cognitive Radio Networks
Walid Saad, Zhu Han, Rong Zheng +3
Unlicensed secondary users (SUs) in cognitive radio networks are subject to an inherent tradeoff between spectrum sensing and spectrum access. Although each SU has an incentive to…
A Cooperative Bayesian Nonparametric Framework for Primary User Activity Monitoring in Cognitive Radio Network
Walid Saad, Zhu Han, H. Vincent Poor +2
This paper introduces a novel approach that enables a number of cognitive radio devices that are observing the availability pattern of a number of primary users(PUs), to cooperate…
On X-Channels with Feedback and Delayed CSI
Ravi Tandon, Soheil Mohajer, H. Vincent Poor +1
The sum degrees of freedom (DoF) of the two-user MIMO X-channel is characterized in the presence of output feedback and delayed channel state information (CSI). The number of anten…
