Resource allocation for heterogeneous multiuser OFDM-based cognitive radio networks with imperfect spectrum sensing
—In this paper we study the resource allocation in OFDM-based cognitive radio (CR) networks, under the consideration of many practical limitations such as imperfect spectrum sens...

Maximizing system throughput by cooperative sensing in Cognitive Radio Networks
—Cognitive Radio Networks allow unlicensed users to opportunistically access the licensed spectrum without causing disruptive interference to the primary users (PUs). One of the ...

A Spectrum-Shaping Perspective on Cognitive Radio
A new perspective on cognitive radio is presented for the case where the primary transmission is in uncoded analog form. The basic idea is to exploit signal-to-noise ratio margins ...
