Performance Analysis of Eigenvalue Based Spectrum Sensing under Frequency Selective Channels
Sener Dikmese, Markku Renfors · 2012
Detecting primary signals with very low Signal-to-Noise Ratio (SNR) is a very important problem in cognitive radio (CR) systems. Small parameter uncertainties are unavoidable in any practical system, and especially the noise variance uncertainty has great effect on the performance of the most basic
