General adapted‐threshold monitoring in discrete environments and rules for imbalanced classes
Statistica Neerlandica, Volume 79, Issue 1, February 2025.Having in mind applications in statistics and machine learning such as individualized care monitoring, or watermark detection in large language models, we consider the following general setting: When monitoring a sequence of observations, Xt, there may be additional information, Zt, on the environment which should be used to design the monitoring ...

On the Secrecy Capacity of Fading Channels
, 2006 We consider the secure transmission of information over an ergodic fading channel in the presence of an eavesdropper. Our eavesdropper can be viewed as the wireless counterpart of Wyner's wiretapper. The secrecy capacity of such a system is characterized

Transmit design for MIMO wiretap channel with a malicious jammer
, 2016 In this paper, we consider the transmit design for multi-input multi-output (MIMO) wiretap channel including a malicious jammer. We first transform the system model into the traditional three-node wiretap channel by whitening the interference at the ...

Secure Communication for Spatially Sparse Millimeter-Wave Massive MIMO Channels via Hybrid Precoding [PDF]
, 2019 In this paper, we investigate secure communication over sparse millimeter-wave (mm-Wave) massive multiple-input multiple-output (MIMO) channels by exploiting the spatial sparsity of legitimate user's channel.

Research on critical SNR and power allocation of artificial noise assisted secure transmission
Tongxin xuebao, 2019 A comprehensive performance analysis of artificial noise (AN) assisted secure transmission in multiple-input single-output (MISO) wiretap channels was presented.It was shown that the AN scheme did not always improve the security,and provided an exact ...
