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...
This Letter analyzes the outage performance of a multiuser bidirectional cooperative cellular network in which one base station (BS) and one out of N mobile stations (MSs) exchange messages with the aid of one amplify-and-forward (AF) relay. Our analysis allows for a practical fading scenario where the MS-relay and the BS-relay channels undergo independent Rayleigh and Rician fading, respectively...
