We focus on a dual-functional multi-input-multioutput (MIMO) radar-communication (RadCom) system, where a single transmitter communicates with downlink cellular users and detects radar targets simultaneously. Several design criteria are considered for minimizing the downlink multi-user interference. First, we consider both the omnidirectional and directional beampattern design problems, where t...

STUDY OBJECTIVE To compare the effects of biphasic defibrillation waveforms and conventional monophasic defibrillation waveforms on the success of initial defibrillation, postresuscitation myocardial function, and duration of survival after prolonged duration of untreated ventricular fibrillation (VF), including the effects of epinephrine. DESIGN Prospective, randomized, animal study. SETTI...

The modulating voltages applied to the DIII-D gyrotrons are controlled by reference signals which are synthesized by arbitrary waveform generators. These generators allow ECH operators to pre-program reference waveforms consisting of ramps, flat tops, and various modulation shapes. This capability is independent of the DIII-D central timing and waveform facilities, which provides the ECH operat...

In this paper, we investigate the problem of low probability of intercept (LPI)-based adaptive radar waveform optimization in signal-dependent clutter for joint radar and cellular communication systems, where the radar system optimizes the transmitted waveform such that the interference caused to the cellular communication systems is strictly controlled. Assuming that the precise knowledge of t...

Multi-input multi-output (MIMO) radar waveform optimization is often sensitive to estimation errors and uncertainty in the initial parameters estimates (i.e., some prior information on the target of interest and scenario). Focusing on this issue, the robust waveform design, which attempts to systematically alleviate this sensitivity by explicitly incorporating a parameter uncertainty model in t...

Spectrally Modulated, Spectrally Encoded (SMSE) waveforms have demonstrated considerable practical utility and remain a viable alternative for Cognitive Radio (CR) -based Software Defined Radio (SDR) applications. As demonstrated in this paper, this utility is greatly enhanced when soft decision selection and dynamic assignment of SMSE design parameters is incorporated. This paper provides the ...

In this paper, the problem of cognitive radar (CR) waveform optimization design for target detection and estimation in multiple extended targets situations is investigated. This problem is analyzed in signal-dependent interference, as well as additive channel noise for extended targets with unknown target impulse response (TIR). To address this problem, an improved algorithm is employed for tar...

1. ABSTRACT New waveform requirements are pushing the limits of traditional modem design techniques. Fortunately, modern Digital-to-Analog Converter (DAC) and Analog-to-Digital Converter (ADC) can achieve sampling rates in the GHz range. These new DACs and ADCs allow designers to directly synthesize channels that have bandwidths of more than 500 MHz+; allowing either wideband or multi-channel m...

As a reflective display technology, electrowetting displays (EWDs) have the advantages of paper-like display, low power consumption, fast response, and full color, but aperture ratio EWDs is seriously affected by oil dispersion charge trapping. In order to improve optimize performance EWDs, combined pulse driving waveform with rising gradient design was proposed. First, an initial voltage estab...

This paper presents the design of a light chamber which can be used to investigate the flicker behaviour of various types of lamps. Using this system, a lamp can be subjected to a controlled voltage waveform while current and illuminance of the lamp are monitored. With the aid of such a voltage source capable of generating voltage fluctuations, including interharmonics and other power quality d...
