Transmitter Optimization in Slow Fading MISO Wiretap Channel
Sanjay Vishwakarma, A. Chockalingam
In this paper, we consider the transmitter optimization problem in slow fading multiple-input-single-output (MISO) wiretap channel. The source transmits a secret message intended f…
MIMO DF Relay Beamforming for Secrecy with Artificial Noise, Imperfect CSI, and Finite-Alphabet
Sanjay Vishwakarma, A. Chockalingam
In this paper, we consider decode-and-forward (DF) relay beamforming with imperfect channel state information (CSI), cooperative artificial noise (AN) injection, and finite-alphabe…
Decode-and-Forward Relay Beamforming with Secret and Non-Secret Messages
Sanjay Vishwakarma, A. Chockalingam
In this paper, we study beamforming in decode-and-forward (DF) relaying using multiple relays, where the source node sends a secret message as well as a non-secret message to the d…
Transmitter Optimization in MISO Broadcast Channel with Common and Secret Messages
Sanjay Vishwakarma, A. Chockalingam
In this paper, we consider transmitter optimization in multiple-input single-output (MISO) broadcast channel with common and secret messages. The secret message is intended for …
Power Allocation in MIMO Wiretap Channel with Statistical CSI and Finite-Alphabet Input
Sanjay Vishwakarma, A. Chockalingam
In this paper, we consider the problem of power allocation in MIMO wiretap channel for secrecy in the presence of multiple eavesdroppers. Perfect knowledge of the destination chann…
Sum Secrecy Rate in Full-Duplex Wiretap Channel with Imperfect CSI
Sanjay Vishwakarma, A. Chockalingam
In this paper, we consider the achievable sum secrecy rate in full-duplex wiretap channel in the presence of an eavesdropper and imperfect channel state information (CSI). We assum…
