The Ultrahigh-Frequency Domain
Transactions of the American Institute of Electrical Engineers, 1937Use of ultrahigh frequencies for educational broadcasting has been thought to offer attractive possibilities because of the supposedly almost unlimited number of channels; however, the demands of other radio services, particularly television, may be expected to congest this newly opened region. Ultrahigh-frequency waves behave somewhat like light waves,

2016 8th International Conference on Electronics, Computers and Artificial Intelligence (ECAI), 2016
In this paper it is presented the second stage analysis used to determine the signal quality coefficient for vibro-acoustic signals. After successfully determining the integrity coefficient in the “first stage analysis on determining the Signal Quality Coefficient in vibro-acoustic domain-waveform integrity analysis” paper a second and deeper analysis ...

Strict Passivity in the Frequency Domain
IFAC Proceedings Volumes, 1992Abstract The notion of strict passivity is defined for systems represented by a set of differential equations. An equivalent definition is formulated in frequency domain terms. The paper shows that the considered systems are strictly passive if and only if a corresponding J-Iossless matrix can be constructed. Several examples are included.

Forecast Combination in the Frequency Domain
SSRN Electronic Journal, 2023Predictability is time and frequency dependent. We propose a new forecasting method - forecast combination in the frequency domain - that takes this fact into account. With this method we forecast the equity premium and real GDP growth rate. Combining forecasts in the frequency domain produces markedly more accurate predictions relative to the standard

Frequency domain chaotic watermarking
ISCAS 2001. The 2001 IEEE International Symposium on Circuits and Systems (Cat. No.01CH37196), 2002A watermarking procedure to be applied in the frequency domain to digital images has been proposed and investigated, with purpose of copyright protection. The selected digital signature is a chaotic sequence embedded by considering a shaping function to weight in different manner each sequence value, as a function of the image properties in the ...

Frequency-Domain Equalization Incorporated with Frequency-Domain Redundancy for OFDM Systems
2006 IEEE 17th International Symposium on Personal, Indoor and Mobile Radio Communications, 2006This paper proposes a frequency-domain equalizer (FEQ) which utilizes not only guard interval but also redundancy in the frequency domain to eliminate inter-symbol and inter-carrier interferences. The proposed FEQ employs the hybrid criterion, i.e., the zero-forcing (ZF) criterion for compensating desired subcarriers and the minimum mean square error ...

IEEE Control Systems, 2000
The author aims to give you some idea of what a pole is and why it is a significant concept. To do this, he gives a tour of the mysterious world that control engineers call the frequency domain. The article is intended as a conceptual preview for undergraduate students and assumes minimal technical background.
