On the statistics of cognitive radio capacity in shadowing and fast fading environments
Abstract--In this paper we consider the capacity of the cognitive radio (CR) channel in a fading environment under a "low interference regime". This capacity depends crit...

On autocorrelation-based multiantenna spectrum sensing for cognitive radios in unknown noise
Recently several time-domain approaches relying on the generalized likelihood ratio test (GLRT) paradigm have been proposed for multiple antenna spectrum sensing in cognitive radi...

A cross-layer design for resource allocation and congestion control in multichannel multi-hop cognitive radio networks
Efficient and fair resource allocation associated with congestion control in multi-hop cognitive radio networks (CRN) is a challenging problem. In this paper, we consider their mu...

Maximize Secondary User Throughput via Optimal Sensing in Multi-Channel Cognitive Radio Networks
In a cognitive radio network, the full-spectrum is usually divided into multiple channels. However, due to the hardware and energy constraints, a cognitive user (also called second...
