In this work, we consider secure communications in wireless multi-user (MU) multiple-input single-output (MISO) systems with channel coding in the presence of a multi-antenna eavesdropper (Eve), who is a legit user trying to eavesdrop other users. In this setting, we exploit machine learning (ML) tools to design soft and hard decoding schemes by using precoded pilot symbols as training data. The proposed ML frameworks allow an Eve to determine the transmitted message with high accuracy. We… Expand

Data-Driven Precoded MIMO Detection Robust to Channel Estimation Errors
Numerical results show that severe CSIT degradation impedes the correct detection when a conventional detector is used, but the proposed learning-based detectors can achieve good detection performance even under severeCSIT deterioration, and can yield 4–8 dB power gain for BER values lower than 10−4 when compared to the classic linear minimum mean square error (MMSE) detector.

Secure Interference Exploitation Precoding in MISO Wiretap Channel: Destructive Region Redefinition With Efficient Solutions
This paper shows that the required transmit power can be further reduced by re-designing the ‘destructive region’ of the constellations for symbol-level precoding and re-formulating the power minimization problem, and studies the SINR balancing problems with the derived ‘complete destructive region' with full, statistical and no Eve’s CSI.
