Research Progress of Physical-layer Security in Multiple Antenna/Multi-carrier Systems
摘要
Abstract
Due to open propagation environments,security issues are everywhere for wireless communications,and have been important research topics in wireless networks.Physical-layer security,which explores the random characteristics of wireless medium to implement the confidential transmission at the physical-layer through technologies such as coding and modulation,is one of important branches for future wireless network security.With wide adoption of advanced physical-layer techniques,such as multiple antenna and multi-carrier,more feasible schemes are available for physical-layer security. Recent research progresses in multiple antenna/multi-carrier based wireless physical-layer security are reviewed,in which a time-domain artificial noise design scheme for orthogonal-frequency-division-multiplexing(OFDM)systems is introduced emphatically.Finally,some potential research directions in future wireless physical-layer security are presented.关键词
