Low-complexity beamforming designs of sum secrecy rate maximization for the Gaussian MISO multi-receiver wiretap channel

This paper studies the beamforming design for sum secrecy rate (SSR) maximization in the Gaussian multiple-input single-output multi-receiver wiretap channel (MISO-MRWC). The optimization problem of finding the optimal beamforming algorithm is non-convex and intractable to solve using low-complexity…
