Cooperative Interference and Power Allocation in a Bidirectional Untrusted Relay Network With Channel Estimation Errors
The secure communication of a two-way untrusted amplify-and-forward relay network under the imperfect channel state information is investigated. To improve the secrecy of the relay wiretap system, artificial noise is introduced into each source signal. The total and the individual power constraint c...
