This paper investigates impact of hardware impairments on the probability of Non-zero Secrecy Capacity (NSC) of multi-hop relay networks. In the considered protocol, multiple eavesdroppers attempt to overhear the data that is relayed from a source to a destination via multiple intermediate relay nodes. To enhance the secrecy performance, the multi-hop randomize-and-forward (RF) strategy is used to...
In this paper, we evaluate performances of various transmit antenna selection (TAS) protocols in underlay cognitive radio network under impact of hardware impairments. In particular, a secondary base station (SB) selects one of available antennas to transmit its data to a secondary user (SU) that randomly appears in radio range of the SB. In the first proposed scheme (named RAND), the SB randomly...
In this paper, the impact of hardware impairments on secrecy performance of cognitive MIMO schemes is investigated. In addition, the relay which helps the source forward the source signal to the destination can operate either half-duplex mode or full-duplex mode. For performance evaluation, we give the expressions of average secrecy rate over Rayleigh fading channel. Monte-Carlo simulations are presented...
