Abstract :
In this paper, we introduce a three-phase transmission scheme for cloud radio networks against eavesdropper. We study the security and reliability performance of this scheme in the form of intercept probability and outage probability, respectively. Channel estimation error is considered in our study instead of assumption of perfect channel state information. It is found that the security-reliability performance improves as the number of relay increases. Moreover, the length of training symbol considerably influences the performance. Simulation results are provided to corroborate our studies.
