BACKGROUND Global System for Mobile Communications (GSM) tele communication
systems provide wireless communication to mobile devices over a radio access network …

Spectrum sensing is one of the key technologies to realize dynamic spectrum access in
cognitive radio systems, especially for the next generation mobile systems. In this paper, the …

Adaptive systems have the ability to respond to environmental conditions by modifying their
processing at runtime. This can be implemented by using partial reconfiguration (PR) on …

The focus of this paper is an experimentation platform known as Iris that has a runtime
reconfigurable software radio at its core. We have employed this platform to enable a wide …

Spectrum sensing is one of the key technologies to realize dynamic spectrum access in
cognitive radio systems, especially being able to reliably detect primary user signal in low …

Cognitive Radio requires the architecture of radio systems to combine reception and
spectrum monitoring functionality efficiently. We propose a flexible digital front end that …

With the explosion of network traffic in the future IMT-advanced system, the revenue for
mobile operators is not increasing anywhere near as fast as the network traffic. This means …

Since multimedia service is recently popularized, the demand for mobile traffic is increasing.
As a method to meet such demand, femtocell network is proposed. However, as femtocell …

As the demand for wireless communication services grows quickly, spectrum scarcity has
been on the rise sharply. In this context, cognitive radio (CR) is being viewed as a new …
