摘要: The performance of energy detection using outdated channel state information (CSI) over Rayleigh fading is studied where a closed form expression for the average probability derived. This unveils dependence on estimated CSI as well correlation function. Using this dependence, we propose novel adaptive sensing-scheduling algorithm that outperforms fixed detector with no information. accuracy derived results verified computer simulations.
