Frequency Aliasing-Based Spatial-Wavenumber Filter for Online Damage Monitoring
Shock and Vibration, 2020 The spatial-wavenumber filter method can extract the specific mode of the Lamb wave, thereby distinguishing the incident wave and the damage reflection wave. This method has been widely studied for damage imaging.

Channel Capacity under General Nonuniform Sampling [PDF]
, 2012 This paper develops the fundamental capacity limits of a sampled analog channel under a sub-Nyquist sampling rate constraint. In particular, we derive the capacity of sampled analog channels over a general class of time-preserving sampling methods ...

‘Almost nonunique’ solutions to parameter estimation in periodic signals
EURASIP Journal on Advances in Signal ProcessingProvided the Nyquist criterion is met, by the Nyquist–Shannon sampling theorem one can reconstruct the signal uniquely using the sampled data. In this work, by means of an algorithm that computes the amplitudes, frequencies and phases of a signal to ...

Design of discrete PI‐PR2 controllers for time‐delayed systems using dominant pole placement method
Asian Journal of Control, EarlyView.Abstract This paper presents a new controller structure known as the proportional‐integral proportional‐double‐retarded (PI‐PR2) designed for discrete‐time systems with time delay. The dominant pole placement technique, which is frequently encountered in control systems, is used as the primary design method. The design method starts that dominant poles

Channel Capacity under Sub-Nyquist Nonuniform Sampling
, 2014 This paper investigates the effect of sub-Nyquist sampling upon the capacity of an analog channel. The channel is assumed to be a linear time-invariant Gaussian channel, where perfect channel knowledge is available at both the transmitter and the ...
