Abstract

Under the assumption of outdated CSI, the transmission design and secrecy performance in cooperative networks is studied. Using the delay correlation model, the source first estimates the connection outage probability (COP) and secrecy outage probability (SOP), respectively, thus the secrecy information can be encoded into a Wyner code with proper rate pair. If the destination does not decode but the relay does, an opportunistic decode-and-forward (ODF) cooperation would be implemented to help the transmission. Some new insights into the secrecy performance of ODF are provided via the analysis of reliability-security tradeoff (RST) and secrecy throughput.
