This paper proposes a new distributed space-time block code (DSTBC) over frequency-selective fading channels for two-hop amplify and forward relay networks, consisting of a source node, two relay nodes ( and ), and a destination node.
Sakran et al. in [16] proposed a secure relay selection scheme which selects a trusted decode and forward relay to assist the SUs and maximize the achievable secrecy rate that is subjected to the interference power constraints at the PUs for the different number of eavesdroppers and PUs under available channel knowledge in the security constrained CRNs.
