Hybrid Cooperative Energy Detection Techniques in Cognitive Radio Networks
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 unlicensed Secondary Users (SUs) through robust and efficient Spectrum Sensing (SS). Energy Detection (ED) is the dominantly used SS approach owing to its low computational complexity and ability to identify spectrum holes without requ...
متن کاملHybrid Cooperative Energy Detection Techniques in Cognitive Radio Networks
A rapid growth in wireless communications over the last decade has resulted in an ever growing demand for radio spectrum. 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 unlicensed secondary users (SUs) through robust and efficient spectrum sensing (SS). Energy detection (ED) is the...

متن کاملPerformance of Hybrid-MIMO Receiver Scheme in Cognitive Radio Network
In this paper, we evaluate the performance of the Hybrid-MIMO Receiver Scheme (HMRS) in Cognitive Radio network (CR-network). We investigate the efficiency of the proposed scheme which the energy level and user number of primary user are varied according to the characteristic of CR-network. HMRS can allow users to transmit either Space-Time Block Code (STBC) or Spatial-Multiplexing (SM) streams...
متن کاملPerformance Evaluation of Spectrum Sensing Techniques in Cognitive Radio Network
Cognitive radio (CR) is a promising technique that offers a solution to the spectrum scarcity problem by dynamically exploiting the underutilization of the spectrum among the bands. There are numerous procedures to detect spectrum using CRs like energy detection (ED), matched filter detection (MFD), cyclostationary feature detection (CFD), waveform based detection (WBD) and so on. In this paper...
