Free registration required

Executive Summary

To overcome the problem of the under-utilization of the licensed spectrum in Cognitive Radio Networks (CRN), the Secondary Users (SU) can share the licensed spectrum with the Primary Users (PU). It is reasonable to perform the cooperation among the Secondary Users and the Primary Users (PUs). The utilization of rateless coding is suitable for the opportunistic spectrum access of cognitive radio, there has been some work in this area, however, the cognitive communication consider both direct transfer mode and multi-relay transfer mode with rateless coding has not been carefully investigated. In this paper, a novel cooperation strategy based on rateless coding is proposed to perform relay cooperation in CRN .
