Opportunistic Relay Selection for Decode-and-Forward Two-Way Relaying under Outdated Channel State Information

—The Channel State Information (CSI) plays a significant role in wireless Relay Selection (RS) systems. Due to the time variation of channels, the CSI in the data transmission phase may differ (i.e., is outdated) from that in the relay selection phase. Addressing this issue, the Decode-andForward (DF) Two-Way Relaying (TWR) network is considered, and the… (More)
