Cognitive Radio and Dynamic Spectrum Sharing Systems
The vision behind software radio (SR) is to realize the communication specific signal processing of a radio as far as possible on programmable hardware. An ideal SR samples the received signal directly at the antenna, and its hardware consists of a general purpose processor that is connected with analog-to-digital and with digital-to-analog converters. A radio that uses an analog radio frontend...
متن کاملDynamic Spectrum Sharing in Cognitive Radio Femtocell Networks
Femtocell is envisioned as a highly promising solution to tackle the communications in the indoor environments, which has been a very challenging problem for mobile network operators. Currently, the spectrum allocated to femtocells is from the same licensed spectrum of macrocells, and the same mobile network operator. In this case, the capacity of femtocell networks may be largely limited due t...
متن کاملDynamic Intra –network Spectrum Sharing for Cognitive Radio Networks
The swift expansion in the wireless technology has shaped the spectrum bandwidth scarce. This lack of spectra has pushed the spectrum management authorities to devise new ways for the efficient utilization of the existing spectrum. According to Federal Communication Commission (FCC) more than 70% of the available spectrum is not utilized optimally. Due to the shortage of available frequencies t...
متن کاملSpectrum Access and Sharing for Cognitive Radio
Cognitive radio (CR) has emerged as a smart solution to spectrum bottleneck faced by current wireless services, under which licensed spectrum is made available to intelligent and reconfigurable secondary users. CR technology enables these unlicensed secondary users to exploit any spectrum usage opportunity by adapting their transmission parameters on the run. In this chapter, the authors discus...
متن کاملDynamic Spectrum Sharing in Cognitive Radio Networks: a Solution based on Multiagent Systems
In modern day wireless networks, spectrum utilization and allocation are static. Generally, static spectrum allocation is not a feasible solution considering the distributed and dynamic nature of wireless devices, thus some alternatives must be ensured in order to allocate spectrum dynamically and to mitigate the current spectrum scarcity. An effective technology to ensure dynamic spectrum usag...
