This paper covers an extensive detailed analysis about the use of cooperative communication in cognitive radio especially the underlay technique. Authors have also tried to explain the effect of using multiple relay instead of single relay on outage probability. Asymptotic analysis of the proposed system model is also derived and results are compared. This papers explains the use cooperative communication...
In this paper authors have tried to explain single relay model of cooperative communication with underlay spectrum sharing mode with two different possibilities of transmission i.e. with and without diversity along with their asymptotic analysis. Authors have tried to explain both transmission in comparison form through the graphical results and verified by asymptotic results.
