OTFS Radar Waveform Design Based on Information Theory

Entropy
In this work, we consider the waveform design for radar systems based on orthogonal time–frequency space (OTFS). The conditional mutual information (CMI), chosen as a promising metric for assessing the radar cognitive capability, serves as the criterion ...

Optimisation of practically constrained waveforms for Rician target detection with multiple‐input‐multiple‐output radar

IET Radar, Sonar & Navigation, 2022
In this paper, the waveform design for Rician target detection with multiple‐input‐multiple‐output radar is addressed. The relative entropy between the distributions of the observations under two hypotheses is employed as the design metric.

What is sought from graphic designers? A first thematic analysis of job offers for graphic design positions in the United Kingdom

, 2016
An empirically grounded understanding about which knowledge and skills that are sought from designers is missing for a number of professional subfields of design. This gap in research challenges i) design educators in planning their educational offerings

Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

Advanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

Atom Probe Tomography as an Emerging Tool for Understanding Defect‑Driven Mechanisms in HfO2‑Based Ferroelectrics

Advanced Functional Materials, EarlyView.
This Perspective highlights atom probe tomography as a powerful tool for understanding the atomic‐scale defect chemistry in HfO2‐based ferroelectrics. 3D mapping of dopants, point defects, and interface chemistry can provide new insight into defect‐driven mechanisms underpinning the ferroelectricity in the system and guide the design of more reliable ...

Modulation Design for Integrated SWIPT Receivers With OFDM-Based Waveforms

IEEE Open Journal of the Communications Society
In this paper, we propose a novel simultaneous wireless information and power transfer (SWIPT) technique that employs orthogonal frequency-division multiplexing (OFDM)-based waveforms. The proposed scheme jointly designs particular characteristics of the

GNSS Signal Design Approach Considering Receiver Performance [PDF]

, 2008
In this work we establish a systematic approach to design optimum chip pulse shapes for DS-CDMA systems which are absolutely band-limited, whose energy is mainly concentrated in one chip duration, and that minimize the Cramer-Rao lower bound for the ...

Memristive‐Gated RC‐Delay Synaptic Transistors for Time‐Encoded Analog in‐Memory Computing

Advanced Functional Materials, EarlyView.
A Memristive‐Gated Transistor for Time‐Encoded Analog In‐Memory Computing — By exploiting the RC delay of a self‐rectifying interface‐type memristor, nonlinear I–V distortion is structurally bypassed, enabling 3‐bit nonvolatile memory, spike‐timing‐based analog encoding, and hardware‐calibrated reservoir‐computing validation within a unified device ...

Constrained Transmit Beampattern Design Using a Correlated LFM-PC Waveform Set in MIMO Radar

Sensors, 2020
This paper considers the design of a desired transmit beampattern under the good ambiguity function constraint using a correlated linear frequency modulation-phase coded (LFM-PC) waveform set in multiple-input-multiple-output (MIMO) radar. Different from
