PERFORMANCE OF WAVELET PACKET BASED SPECTRUM SENSING IN COGNITIVE RADIO FOR DIFFERENT WAVELET FAMILIES
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 5
Abstract
Spectrum sensing has been identified as a key enabling functionality to ensure that cognitive radios would not interfere with primary users, by reliably detecting primary user signals. The cognitive Radio built on a softwaredefined radio, defined as an unpredictable growth of wireless communication scheme, which is automatic adjustment of the electromagnetic environment to adapt their operation and dynamically vary its radio operating parameters while bring no harmful interference to the primary use. The researchers are focuses on the cooperative spectrum sensing technique to improve reliability of the spectrum but for cooperative spectrum sensing scheme are very difficult to tolerate with each individual node of the wireless network for the short time. This paper proposes energy detection based spectrums sensing for the different SNR. The proposed method which is also analysis performance of the SNR and the Decision Accuracy using different wavelet family and comparative analysis of the Haar, Symlets ,Coiflets and Dabuchesis wavelet in terms of different value of the SNR , Probability of Detection.
