… , we propose secrecy rate … a secure communication network consisting of a legitimate user
and an eavesdropper, where our goal is to minimize the transmit power with a secrecy rate con…

… We refer to this scheme as Secure Superposition Coding scheme. The available resources

… a new secure transmission scheme under the constraints of transmit power and secrecy …
fixes the communication rate and adaptively adjusts the secrecy rate and the transmit power …

… Then we propose a simple cooperative secure transmission strategy, where the source only
communicates with relays at the first stage and distributed beamforming is then adopted by …

… the problem of secure communication with multi-antenna transmission in fading channels. …

… We present an alternative secrecy outage … transmissions fail to achieve perfect secrecy.
Using this formulation, we design two transmission schemes that satisfy the given security …

… For scenario (b), the secrecy rate based design is not applicable and we consider a QoS
based robust secure transmission design to provide security. Our strategy here is to maximize …
