Physical Layer Security through Secure Channel Estimation

摘要: The random nature of wireless channel can be utilized to achieve secure communications. Recently, there have been some contributions towards finding practical approaches provide physical layer security, but robust and estimates are critical in achieving secrecy. In this paper, we propose that in-band full-duplex communication by the legitimate transceiver pair mask from eavesdropper. proposed estimation technique comprises two stages. first stage, self- interference is estimated respective nodes. second transmission both nodes at while providing equivocation performance analysis shows scheme provides maintaining
