PERFORMANCE ANALYSIS OF SPECTRUM SENSING USING UNDER SAMPLING FOR COGNITIVE RADIO

The deficiency of the spectrum range is major issue in communication technology to augment the new standard of communication. The reuse of spectrum is become a way to effectively use the spectrum. To perform this, spectrum sensing is required for reuse of spectral hole. There are several techniques to perform spectral sensing. This paper is explained the spectrum sensing using under sampling method. The spectrum hole detection accuracy is key parameter to evaluate the performance of this method. The results have been given in different noisy environment.
