A Robust PAST-Based ESPRIT Algorithm With Variable Forgetting Factor and Regularization for Frequencies/Harmonics Estimation in Impulsive Noise

Jian-Qiang Lin et al.

Summary: This article proposes a robust recursive ESPRIT algorithm with variable forgetting factor (VFF) and variable regularization (VR) for online frequencies/harmonics estimation. The algorithm is based on the projection approximation subspace tracking method and incorporates the locally optimal FF (LOFF) scheme. It reduces estimation variance in signal fading scenarios with the use of the VR scheme and employs a robust statistics-based M-estimate objective function to suppress the adverse effect of impulsive noise.

Scalable ESPRIT Processor for Direction-of-Arrival Estimation of Frequency Modulated Continuous Wave Radar

Yongchul Jung et al.

Summary: ESPRIT processor is an algorithm for estimating the direction-of-arrival of signals based on the shift-invariant properties of array antennas. It supports scalable antenna configurations and achieves better performance by simplifying computational methods to reduce execution time. The processor was designed using HDL and underwent FPGA-based verification, resulting in significant reductions in slice registers, LUTs, and DSPs compared to existing structures.

Compressive Sensing Taylor-Fourier and Windowing Approach for Synchronized Phasor, Frequency and ROCOF Measurements

Guglielmo Frigo et al.

Summary: Modern distribution networks have higher distortion and wider variability in voltages and currents, requiring new techniques to reduce latency and limit the impact of spurious components. The Taylor-Fourier Multifrequency approach is a suitable candidate for Phasor Measurement Units in distribution systems. An improved version of this method, utilizing window functions for support identification and estimation, has been proposed and shown enhanced accuracy under non-standard test conditions.
