A Cognitive Radio Approach for Usage of Virtual Unlicensed Spectrum
While essentially all of the frequency spectrum is allocated to different applications, observations provide evidence that usage of the spectrum is actually quite limited, particularly in bands above 3 GHz. In this paper we present a Cognitive Radio approach for usage of Virtual Unlicensed Spectrum (CORVUS), a vision of a Cognitive Radio (CR) based approach that uses allocated spectrum in a opp...
متن کاملSmart Radio Spectrum Management for Cognitive Radio
Today’s wireless networks are characterized by fixed spectrum assignment policy. The limited available spectrum and the inefficiency in the spectrum usage necessitate a new communication paradigm to exploit the existing wireless spectrum opportunistically. Cognitive radio is a paradigm for wireless communication in which either a network or a wireless node changes its transmission or reception ...
متن کاملTraffic Analysis with Cognitive Radio Spectrum
Most of the existing DSA schemes are the unlicensed user, traffic in a licensed spectrum without compromising the transmissions of the licensed users, in which all the unlicensed users are typically treated equally. Dynamic spectrum access (DSA) is an important design aspect for the cognitive radio networks. Specifically, the unlicensed user traffic is divided into two priority classes (i.e., h...
متن کاملSpectrum Occupancy Analysis for Cognitive Radio
Observations provide evidence that the licensed spectrum is by far not fully used neither in time nor in space. Cognitive radio, which can sense its environment and location and then alter its frequency, modulation and other parameters so as to dynamically reuse the available spectrum, could break the current spectrum availability bottleneck. The fundamental aspect to the success of such techno...
متن کاملSpectrum Sensing In Cognitive Radio Using Matlab
The radio frequency spectrum is a scarce natural resource and its efficient use is of the utmost importance. The spectrum bands are usually licensed to certain services, such as mobile fixed broadcast, and satellite, to avoid harmful interference between different networks. Most spectrum bands are allocated to certain services but worldwide spectrum occupancy measurements show that only portion...
