摘要：

A design based on network coding is presented to improve the secrecy capacity of the cooperative communication system where a amplify-and-forward relaying is employed. The system consists of two source nodes, one destination node and one eavesdropper. For a single session between one source and the destination, we derive the approximate formula of secrecy capacity in the high SNR regime. Through detailed computer simulation, we evaluate the effect of node's location on the secrecy capacity in the multiple-access relay channel. 1548-7741/Copyright © 2014 Binary Information Press.
