On the LoRa Modulation for IoT: Waveform Properties and Spectral Analysis [PDF]
IEEE Internet of Things Journal, 2019 An important modulation technique for Internet of Things (IoT) is the one proposed by the low power long range (LoRa) alliance. In this paper, we analyze the $M$ -ary LoRa modulation in the time and frequency domains.

Matched Illumination Waveforms using Multi-Tone Sinusoidal Frequency Modulation [PDF]
arXiv, 2021 This paper explores the design of constant modulus Matched-Illumination (MI) waveforms using the Multi-Tone Sinusoidal Frequency Modulation (MTSFM) waveform model. MI waveforms are optimized for detecting targets in known noise and clutter Power Spectral Densities (PSDs).

Adaptive Transmit Waveform Design using Multi-Tone Sinusoidal Frequency Modulation [PDF]
IEEE Transactions on Aerospace and Electronic Systems, vol. 57,
no. 2, pp. 1274-1287, April 2021, 2020 This paper presents an adaptive waveform design method using Multi-Tone Sinusoidal Frequency Modulation (MTSFM). The MTSFM waveform's modulation function is represented as a finite Fourier series expansion. The Fourier coefficients are utilized as a discrete set of design parameters that may be modified to adapt the waveform's properties.

Anesthesia & Analgesia, 2018 Monitoring cardiac output is of special interest for detecting early hemodynamic impairment and for guiding its treatment. Among the techniques that are available to monitor cardiac output, pressure waveform analysis estimates cardiac output from the shape of the arterial pressure curve.

A chemical waveform synthesizer [PDF]
Proceedings of the National Academy of Sciences, 2005 Algorithms and methods were developed to synthesize complex chemical waveforms in open volumes by using a scanning-probe microfluidic platform. Time-dependent variations and oscillations of one or several chemical species around the scanning probe, such as formation of sine waves, damped oscillations, and generation of more complex patterns, are ...

Enhanced Hybrid TIM-TDMA to Maximize the Total Throughput With Fairness Constraints
IEEE Open Journal of the Communications SocietyThis paper addresses the problem of topological interference management (TIM) in ad hoc networks operating under a frequency-flat Rayleigh fading channel in single-input single-output (SISO). Assuming that the nodes have access to the statistical channel

Medial entorhinal cortex activates in a traveling wave in the rat
eLife, 2020 Traveling waves are hypothesized to support the long-range coordination of anatomically distributed circuits. Whether separate strongly interacting circuits exhibit traveling waves remains unknown.
