Integrating large amounts of wind power into power systems brings a large influence on the dynamic frequency response characteristic (DFRC). The traditional low-order system frequency response (SFR) model is no longer applicable at the current time. Based on the small signal analysis theory, a set of novel low-order SFR models for doubly-fed induction generator (DFIG) distributed wind power gen...

An analytical method for lignins has been developed that involves derivatization followed by reductive cleavage (DFRC), depolymerization, and quantitative (31)P NMR spectroscopy. This technique detects and quantifies the various ether linkages present in softwood residual kraft lignins (RKL) and milled wood lignins (MWL). In addition, the technique supplies new quantitative information about be...

Dual-Functional Radar-Communication (DFRC) system is an essential and promising technique for beyond 5G. In this work, we propose a powerful unified multi-antenna DFRC transmission framework, where additional radar sequence transmitted apart from communication streams to enhance beampattern matching capability, Rate-Splitting Multiple Access (RSMA) adopted better manage the interference. RSMA r...

Conventional radars repeat the transmission of same waveform after a predefined interval time called pulse-repetition-interval (PRI). This technique helps estimate range and Doppler shift targets suppress clutter. However, in dual-function radar communication (DFRC), different symbol is transmitted each PRI. Depending on number targets, receiver output yields several peaks representing targets’...

Despite the growing importance of Eucalyptus wood as raw material for pulp and paper, there is a lack of knowledge on the chemistry of their macromolecular components. The present paper addresses this issue by applying the recently developed protocol for isolating enzymatic mild acidolysis lignins (EMAL) from Eucalyptus grandis, Eucalyptus globulus and the softwood species Douglas fir and white...

This paper deals with the Dual-Function Radar and Communication (DFRC) signal design for a Multiple-Input–Multiple-Output (MIMO) system, considering presence of signal-dependent clutter. A modulation methodology called Spectral Position Index Amplitude (SPIA) is proposed, which involves selecting passband stopband positions applying amplitude modulation. Signal to Interference plus Noise Ratio ...
