Spectrum Sensing and Error Rate Analysis by Cognitive Radio Users using Welch’s Power Spectral for High Data Rate Applications
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 3
Abstract
Cognitive radio is a technique which overcomes the spectrum underutilization. One of the key techniques of Cognitive radio is spectrum sensing. By using Energy detection technique, we evaluate the presence or absence of the signal in the received frequency band of a spectrum. Evaluated Bit Error Rate (BER) by using conventional periodogram and Welch’s power spectrum density and compared the results. In this survey, we can able to prove that BER reduction using Welch’s spectral density is more efficient than conventional periodogram techniques.
