Joint Waveform Design and Passive Beamforming for RIS-Assisted Dual-Functional Radar-Communication System

IEEE Transactions on Vehicular Technology, 2021
Dual-functional radar-communication (DFRC) technique has been viewed as a promising component in the emerging platforms. When synthesizing the desired transmit beampattern, the degrees of freedom of waveform design is limited, which introduces high multi-

Accurate LPI Radar Waveform Recognition With CWD-TFA for Deep Convolutional Network

IEEE Wireless Communications Letters, 2021
Automotive radars, with a widespread emergence in the last decade, have faced various jamming attacks. Utilizing low probability of intercept (LPI) radar waveforms, as one of the essential solutions, demands an accurate waveform recognizer at the ...

Ventilator Waveforms

Topics in Companion Animal Medicine, 2013
Ventilator waveforms are graphic representations of changes in pressure, flow, and volume within a ventilator circuit. The changes in these parameters over time may be displayed individually (scalars) or plotted one against another (pressure-volume and flow-volume loops).

Timing Waveform Analysis

Critical Care Nursing Clinics of North America, 1996
This article provides a description of correct balloon pump timing as well as the potential timing errors that can occur. There are many factors in addition to timing that can affect the altered arterial waveform during balloon pumping. When analyzing the waveform for appropriate timing, it is important to consider factors associated with the patient ...

Nonlinear waveform generation

Computer Methods and Programs in Biomedicine, 1990
We developed three analog logic SPICE (Simulation Program with Integrated Circuit Emphasis, developed at the University of California, Berkeley, CA) subcircuits, a voltage comparator and a nonlinear waveform generator to compliment the previously derived functions (Goldstein and Rypins, Comput. Methods Programs Biomed.

Arterial waveform analysis

Best Practice & Research Clinical Anaesthesiology, 2014
The bedside measurement of continuous arterial pressure values from waveform analysis has been routinely available via indwelling arterial catheterization for >50 years. Invasive blood pressure monitoring has been utilized in critically ill patients, in both the operating room and critical care units, to facilitate rapid diagnoses of cardiovascular ...
