Gelecek Nesil Ağlar için Spektrum tahsisinde Yeni Bir Yaklaşım: Bilişsel Radyo

Year 2012, Volume: 4 Issue: 1, 25 - 32, 15.01.2012

Abstract

Günümüz kablosuz iletişiminde her bir teknolojiye belirli otoriteler tarafından lisans verme yöntemiyle sabit bir spektrum atama politikası uygulanmaktadır. Farklı teknolojilerin gelişmesi, artan kullanıcı talepleri, mevcut sınırlı spektrumun verimsiz olarak kullanımı yeni bir iletişim teknolojisi kavramının ortaya çıkmasına ve bu teknolojinin hızla gelişmesine neden olmuştur. Yeni nesil ağlar olarak da adlandırılan bilişsel radyo teknolojisiyle spektrumun verimli ve dinamik kullanılması sonucu iletişimin kesintisiz ve daha hızlı olarak yapılması amaçlanmaktadır. Bu çalışmada kablosuz iletişimin gelişmesinde bir dönüm noktası olmaya aday olması nedeniyle bilişsel radyo teknolojisi ele alınmıştır. Bilişsel radyo teknolojisinin temel bilgileri, özellikleri ve kullandığı teknikler açıklanmıştır. Özellikleri ve kullandığı teknikler açısından klasik radyo ve yazılım tanımlı radyo ile karşılaştırılmıştır. Bilişsel radyo konusunda yapılan çalışmalar ve karşılaşılan zorluklar incelenmiştir.

A New Approach in Spectrum Allocation for Next Generation Networks: Cognitive Radio

Year 2012, Volume: 4 Issue: 1, 25 - 32, 15.01.2012

Abstract

In today’s wireless communication, a fixed spectrum assignment policy is implemented for each technology by some authorities. Development of different technologies, increase in users’s demands, inefficient usage of limited spectrum enable to emerge a new communication network paradigm and its rapid improvement. Cognitive radio networks which are also known as next generation networks aim to communicate continuously and rapidly as a result of using spectrum efficiently and dynamically. In this paper, due to having a key role for developing wireless communication systems, the cognitive radio technology is investigated. Basic principles and characteristics of cognitive radio networks and the techniques used by cognitive radio are explained. The specifications and the techniques are compared with classic radio and software defined radio. The proposed studies and challenges encountered are discussed.
