The rapid increase in the mobile device and the different types of wireless communication
has led to the necessity of the extra spectrum allocation for the proper transmission of the …

Spectrum scarcity is one of the major challenges that the modern communication engineers
are going through because of inefficient utilization of allocated frequency spectrum. The …

In this paper, we have proposed a novel approach using Fuzzy Logic System (FLS) for the
potential management of the spectrum access. We have used four descriptors such as …

Introduction of flexibility and intelligence in the wireless devices and applications have
introduced the concept of Cognitive Radio. This research objective has inspired various …

Cognitive radio (CR) is an emergent communication platform that offers solutions for
spectrum scarcity issues. Cognitive radio networks (CRNs) will offer increased bandwidth to …

Cognitive radio (CR) is the enabling technology for supporting dynamic spectrum access:
the policy that addresses the spectrum scarcity problem that is encountered in many …

ABSTRACT A basic problem facing the future in wireless systems is where to find suitable
spectrum bands to fulfill the demand of future services. While all of the radio spectrum is …

In the cognitive radio scenario, the secondary user (SU) detects the vacant spectrum holes,
coordinates this information among the other secondary users and selects the most suitable …

The efficient use of available licensed spectrum is becoming more and more critical with
increasing demand and usage of the radio spectrum. This paper shows how the use of …

Now a days the telecommunication systems have been concerned as a required for a life,
the number of users are improved therefore the usage of spectrum are increased. From …
