Energy-Efficient Subcarrier Pairing and Power Allocation for DF Relay Networks with an Eavesdropper

Algorithms for joint subcarrier pairing and power allocation are investigated in order to maximize the worst-case energy efficiency (EE) in dual-hop decode-and-forward (DF) relay networks in the presence of an active eavesdropper. Accordingly, we study the impact of number of subcarriers on the trad...
