Advanced Science, EarlyView.Rational engineering of terminal substituents in symmetric azobenzene‐based molecules enables precise control over conformationally coupled charge‐transfer processes. This design yields tunable nonvolatile resistive memory behaviors, ranging from write‐once‐read‐many‐times (WORM) to rewritable switching.

Information theory and radar waveform design [PDF]
IEEE Transactions on Information Theory, 1993 Summary: The use of information theory to design waveforms for the measurement of extended radar targets exhibiting resonance phenomena is investigated. The target impulse response is introduced to model target scattering behavior. Two radar waveform design problems with constraints on waveform energy and duration are then solved.

Phase-Coded Waveforms and Their Design
IEEE Signal Processing Magazine, 2009The design of radar waveforms has received considerable attention since the 1950s. In 1953, P.M. Woodward (1953; 1953) defined the narrowband radar ambiguity function or, simply, ambiguity function. It is a device formulated to describe the effects of range and Doppler on matched filter receivers.

The Design of Trellis Waveform Coders
IEEE Transactions on Communications, 1982New algorithms for the design of trellis encoding data compression systems are described. The mare algorithm uses a training sequence of actual data from a source to improve an initial trellis decoder. An additional algorithm extends the constraint length of a given decoder.

Robust Waveform Design for MIMO Radars
IEEE Transactions on Signal Processing, 2011The problem of robust waveform design for multiple-input, multiple-output radars equipped with widely spaced antennas is addressed here. Robust design is needed as a number of parameters may be unknown, e.g., the target scattering covariance matrix and the disturbance covariance matrix.

Waveform Design for Tracking Systems
2015 International Conference on Cyber-Enabled Distributed Computing and Knowledge Discovery, 2015An adaptive waveform selection algorithm for target tracking systems in wideband environments is developed based on the minimization of the mean square tracking error which can be computed using the Cramer-Rao lower bounds. The performance advantage of the proposed adaptive waveform selection algorithm compared with minimum and maximum time band width ...

A steganographic approach for covert waveform design
MILCOM 2016 - 2016 IEEE Military Communications Conference, 2016A framework for designing covert sonar waveform and assessment of its steganographic security for sonar applications is presented, based on a model for the underwater ambient acoustic environment the waveform is intended to hide under. Adopting the lessons from the steganography literature, steganographic security is measured not by evaluating ...

A flexible design of waveform for communication and navigation
2018 IEEE Wireless Communications and Networking Conference (WCNC), 2018The main problem of the integrated waveform design for communication and navigation is timing. The timing accuracy requirement in navigation systems is much higher than that in communication systems. In order to solve this problem, a flexible design of waveform and its tracking algorithm is proposed in this paper.

Radar waveform design for detection of weapons
2010 2nd International Workshop on Cognitive Information Processing, 2010We present waveform design based on signature exploitation techniques for improved detection of weapons in urban sensing applications. We consider a single-antenna monostatic radar system. Under the assumption of exact knowledge of the target orientation and, hence, known impulse response, matched illumination approach is used for optimal target ...
