Spectrum Sharing In Dynamic Spectrum Access Networks
A study by Federal Communication Commission shows that most of the spectrum in current wireless networks is unused most of the time, while some spectrum is heavily used. Recently dynamic spectrum access (DSA) has been proposed to solve this spectrum inefficiency problem, by allowing users to opportunistically access to unused spectrum. One important question in DSA is how to efficiently share s...
متن کاملDynamic Spectrum Sharing by Opportunistic Spectrum Access with Spectrum Aggregation
The rapid growth of wireless services and the breakneck proliferation of wireless devices continue to strain limited spectrum resource. While the need for efficient spectrum sharing mechanisms has been emphasised, opportunistic spectrum access has been considered as a promising mechanism for dynamic spectrum sharing. However, although the idle spectrum could exist, it is usually rather fragment...
متن کاملSpectrum sharing through distributed coordination in dynamic spectrum access networks
Spectrum sharing in open spectrum systems is a challenging problem, particularly since users experience dynamic spectrum availabilities that vary over time and location. In the absence of any centralize infrastructure, users coordinate their spectrum usage to support fair access of spectrum and avoid interference. One critical challenge is to construct an efficient signalling path in the presen...
متن کاملMillimeter-Wave Spectrum of the NO Dimer
The pure rotational spectrum of the NO dimer, (14N16O)2, has been studied in the 225-400 GHz millimeter-wave region by means of direct absorption in a supersonic jet expansion. Previously, only 4 rotational transitions of (NO)2 had been measured in the microwave region. To these, we have added 66 new millimeter-wave transitions with values of J ranging from 4 to 16 and of Ka from 2 to 7. Most t...
متن کاملDynamic Spectrum Access: Implications of the diffusion of spectrum sharing technology
Like most common natural resources, spectrum is finite and prone to overuse and “crowding”. Most of today’s radio systems are not aware of the spectrum environment and operate in a pre-given, static frequency band. Technologies such as cognitive radio (CR) that enable dynamic spectrum access (DSA) have been proposed to improve efficiency and flexibility in the utilization of spectrum. Such tech...
