Improve of Physical Layer Security Performance of Wireless Relay Communication System

Abstract

Abstract-Due to the broadcast nature of wireless communications, security performance of conventional wireless relay communication system is difficult to be guaranteed. In this paper, security performance of the wireless relay communication system based on physical layer network coding (PLNC) is studied. The theoretical analyses and simulations show that the physical layer security performance of wireless relay communication system can be improved effectively by using PLNC technique. Moreover, this paper also shows that the location of relay node in the network has a big impact on the security performance of system.
