We propose the use of discrete-time all-analog joint source-channel coding over wireless
channels in order to provide protection against eavesdropping. We consider a bandwidth …

Recent results on source-channel coding for secure transmission show that separation
holds in several cases under some less-noisy conditions. However, it has also been proved …

This paper investigates the problem of source-channel coding for secure transmission with
arbitrarily correlated side informations at both receivers. This scenario consists of an …

In this study, the problem of transmitting an independent and identically distributed (iid)
Gaussian source over an iid Gaussian wire-tap channel, with an iid Gaussian known …

We propose adding an irregular quadrature amplitude modulation (QAM) constellation to a
wireless transmission scheme in order to obtain greater control over the signal-to-noise ratio …

Physical layer security has recently been regarded as an emerging technique to
complement and improve the communication security in future wireless networks. The …

In this work we study encoding/decoding schemes for the transmission of a discrete time
analog Gaussian source over a Gaussian wiretap channel. The intended receiver is …

The problem of secure lossy source-channel wiretapping with arbitrarily correlated side
informations at both receivers is investigated. This scenario consists of an encoder (referred …

In this paper we consider secure transmission for the multiple-input, multiple-output, single-
antenna-eavesdropper systems with perfect information of the main channel and only the …

Wireless communication security can be enhanced by leveraging the characteristics of the
physical (PHY) layer, where discriminatory scrambling can be employed at the symbol level …
