Pulsed Waveforms and Intermittently Nonlinear Filtering in Synthesis of Low-SNR and Covert Communications
Alexei V. Nikitin, Ruslan L. Davidchack
In traditional spread-spectrum techniques, a wideband transmit signal is obtained by modulating a wideband carrier by a narrowband signal containing a relatively low-rate message.…

Utilizing Pulse Pileup Effect in Development of Robust Low-SNR Covert Communication Links
Alexei V. Nikitin, Ruslan L. Davidchack
In contrast to other spread-spectrum techniques, wideband pulse trains with relatively low pulse arrival rates may be considered unsuitable for covert communications. The high cres…

Utilizing Pileup Effect and Intermittently Nonlinear Filtering in Synthesis of Covert and Hard-to-Intercept Communication Links
Alexei V. Nikitin, Ruslan L. Davidchack
We outline an approach to physical-layer steganography where the transmitted low-power stego messages are statistically indistinguishable from the Gaussian component of the channel…
