Özet

We formulate a joint beamforming vector and power optimization problem for multi-antenna full duplex transmission systems and show that simultaneous transmissions of information bearing signals of legitimate nodes can be optimized to act as artificial noise against eavesdroppers. The proposed system improves the overall throughput, while maintaining secrecy and QoS levels within desired signal-to-interference-plus-noise ratio bounds, without additional power, as verified via simulations.
