PROJECT TITLE :
Beamforming Optimization for Physical Layer Security in MISO Wireless Networks - 2018
A wireless network of multiple transmitter-user pairs overheard by an eavesdropper, where the transmitters are equipped with multiple antennas, whereas the users and eavesdropper are equipped with a single antenna, is taken into account. At completely different levels of wireless channel data, the problem of interest is beamforming to optimize the users' quality-of-service (QoS) in terms of their secrecy throughputs or maximize the network's energy efficiency below users' QoS. All these issues are seen as very difficult optimization issues with several nonconvex constraints and nonlinear equality constraints in beamforming vectors. The paper develops path-following computational procedures of low complexity and fast convergence for the optimal beamforming resolution. Their practicability is demonstrated through numerical examples.
