In this contribution, a high-resolution parameter estimation algorithm is derived based on the Space-Alternating Generalized Expectation-maximization (SAGE) principle for extracting multipath parameters from the output of sliding correlator (SC). The SC allows calculating channel impulse responses with a sampling rate less than that required by Nyquist criterion, and hence is widely used in rea...

Features for automatic speech recognition (ASR) are typically sampled at about 100 Hz (10 ms analysis step). Recent experiments indicate that the most e cient components of the modulation spectrum of speech for ASR are up to about 16 Hz [1]. Consequently, RASTA processing attenuates modulation frequencies higher than 16 Hz and should in principle allow for a subsequent down-sampling of the feat...

Track induced self-excited vibration is commonly encountered in EMS (electromagnetic suspension) maglev systems, and a solution to this problem is important in enabling the commercial widespread implementation of maglev systems. Here, the coupled model of the steel track and the magnetic levitation system is developed, and its stability is investigated using the Nyquist criterion. The harmonic ...

Data transmission over bandlimited channels requires pulse shaping to eliminate or control intersymbol interference (ISI). Nyquist filters provide ISI-free transmission. Here we introduce a phase compensation technique to design Nyquist filters. Phase compensation can be applied to the square-root of any zero-phase bandlimited Nyquist filter with normalized excess bandwidth less than or equal t...

Based on the celebrated Generalized Nyquist Criterion, this paper presents a new frequency-domain method to analyze impact of governor-turbine systems (GTSs), power system stabilizers (PSSs) and wind turbine generators (WTGs) small disturbance stability in systems. Compared with other common analysis method, can avoid calculations eigenvalues, eigenvectors residues, multiple controllers or WTGs...

A method for determining the dynamic parameters of operator a mobile fire engine based on segway, which fully characterize its properties – delay time and inertia was developed. The development includes four stages. At first stage, problem obtaining analytical relationships is solved. These include frequency characteristics at fixed static parameter. second choice substantiated using criterion ...

It tends to cause system oscillation when the inverter with a phase-locked loop based on proportional integral controller (PI-PLL) is connected weak grid. To improve suppression ability of grid-connected inverter, linear active disturbance rejection applied PLL (LADRC-PLL). Considering influence extended state observer, voltage outer-loop, current inner-loop, and frequency coupling, admittance ...
