Performance Analysis of Fading Channels on Cooperative Mode Spectrum Sensing Technique for Cognitive Radio
Spectrum sensing is the main feature of cognitive radio technology. Spectrum sensing gives an idea of detecting the presence of the primary users in a licensed spectrum. The sensing of radio spectrum is an essential problem in cognitive radio CR networks, where secondary users SUs need to detect the presence of primary users PUs before […]
Analysis and Comparison of Different Spectrum Sensing Technique for WLAN ijtsrd
This Paper explores basic two systems of spectrum sensing Cooperative System and Non Cooperative System. Non Cooperative System includes Energy detector, Match Filter and cyclostationary with a performance analysis of transmitter based detection. It also includes analysis of Match Filter and Cyclostationary under low and high SNR, validating the result and applied the technique for […]
Analysis and Comparision of Different Spectrum Sensing Technique for IEEE 802 11 IJTSRD
The electromagnetic spectrum is natural resources. The use of wireless communication grows day by day but spectrum allocation policies is static, it tends to increase the spectrum scarcity problem. COGNITIVE RADIO refers to advance wireless radio which aims to improve the spectrum utilization by identify unused spectrum from environment. Spectrum sensing proposed the key method […]
Performance Analysis of Bayesian Methods to for the Spectrum Utilization in Cognitive Radio IJTSRD
Cognitive radio is an exciting wireless technology that has been introduced for the efficient used of spectrum. Using cognitive radios (CRs), the secondary users (unlicensed users) are allowed to use the spectrum which is originally allocated to primary users (PUs) as far as the active primary users are not using it temporarily. In order to […]
