Secure Full Duplex OFDM Wireless Communication Based on Phase Relay between the Legitimate Nodes
IET Communications(2020)
Abstract
This study proposes a scheme to realise secure orthogonal frequency-division multiplexing (OFDM) wireless communication between two full duplex nodes-node A and node B. If node A wants to send secret messages to node B, node A and node B transmit the training signal to each other to acquire channel state information (CSI) in the first time frame. Node A acquires the phases of the received signal f...
