Capacity- and Bayesian-Based Cognitive Sensing with Location Side Information
— We investigate spectrum sensing by energy detection based on two different objective functions: a Bayesian sensing cost or the network weighted sum capacity. The Bayesian cost ...

Capacity Impact of Location-Aware Cognitive Sensing
— We study Bayesian detection based cognitive sensing and analyze its impact on the capacity in various cases of location information. In a network of one primary and one cogniti...

Capacity limits of cognitive radio with distributed and dynamic spectral activity
Abstract— We investigate the capacity of opportunistic communication in the presence of dynamic and distributed spectral activity, i.e. when the time varying spectral holes sense...

Effective Capacity Analysis of Cognitive Radio Channels for Quality of Service Provisioning
In this paper, cognitive transmission under quality of service (QoS) constraints is studied. In the cognitive radio channel model, it is assumed that the secondary transmitter sen...
