A RESEARCH ON NON COOPERATIVE HYBRID SPECTRUM SENSING TECHNIQUE

The research designed in this paper is to purpose and implement a Hybrid spectrum sensing technique. As the utilization of wireless devices has been increased, there is a great demand for the radio spectrum .Cognitive Radio is a technology which can sense the spectrum to make the efficient use of resources of spectrum. Sensing of spectrum can be done by using matched filter, energy detection, waveform based detection, cyclostationary feature. Hybrid model is implemented by taking the assumptions for the distance and the SNR value, so it does not require unnecessary time for sensing of every frequency band. Results are formulated on the bases of two parameters probability of false detection and probability of correct detection. The proposed methodology has been implemented in MATLAB and the results obtained are in the form of improvement in Throughput, Energy consumption, Accuracy and improvement in Error. The proposed model has been found efficient when compared to the other spectrum sensing techniques. It has been proved the effective improvement in throughput is by 9.9135% .Thus the results obtained are excellent and this will definitely help researcher for the future development of Cognitive Radio.
