Optimal Power Allocation for Two-Way Decode-and-Forward OFDM Relay Networks
Fei He, Yin Sun, Xiang Chen +2
This paper presents a novel two-way decode-and-forward (DF) relay strategy for Orthogonal Frequency Division Multiplexing (OFDM) relay networks. This DF relay strategy employs mult…

Optimal Power Allocation for OFDM-Based Wire-Tap Channels with Arbitrarily Distributed Inputs
Haohao Qin, Yin Sun, Xiang Chen +2
In this paper, we investigate power allocation that maximizes the secrecy rate of orthogonal frequency division multiplexing (OFDM) systems under arbitrarily distributed inputs. Co…
