Abstract

In this paper, an algorithm for sharing the optimal transition primer spectrum in cognitive radio network (CR, Cognitive Radio) was studied and analyzed. The content of the article is mentioned through the optimal decoding protocol, analyzing the network performance of perceived users, the effect of spectrum sharing noise is considered to be associated with the operation of the main user. And a floating forward optimization solution that relies on the probability of power loss reduces the influence of noise on the performance of the network being analyzed, confirms theoretical accuracy and is demonstrated through simulation results Matlab.
