Collision-resistant multi-channel M-ASPM configurations with shared single detection channel
Alexei V. Nikitin, Ruslan L. Davidchack
M-ary Aggregate Spread Pulse Modulation (M-ASPM) is a physical layer (PHY) modulation technique that offers several advantages for low-power wide-area networks (LPWANs). For instan…
Solid-liquid interfacial free energy from computer simulations: Challenges and recent advances
Nicodemo Di Pasquale, Jesus Algaba, Pablo Montero de Hijes +12
The theory of interfacial properties in liquid-liquid or liquid-vapour systems is nearly 200 years old. The advent of computational tools has greatly advanced the field, mainly thr…
M-ary Aggregate Spread Pulse Modulation in LPWANs for IoT applications
Alexei V. Nikitin, Ruslan L. Davidchack
In low-power wide-area networks (LPWANs), various trade-offs among the bandwidth, data rates, and energy per bit have different effects on the quality of service under different pr…
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…
