A compressive MUSIC spectral approach for identification of closely-spaced structural natural frequencies and post-earthquake damage detection
TLDR
Results suggest that the adopted approach for identifying resonant frequencies of white-noise excited structures using acceleration measurements acquired at rates significantly below the Nyquist rate is robust and noise-immune while it can reduce data transmission requirements in acceleration wireless sensors for natural frequency identification and damage detection in engineering structures.About:

Sparse Sensing With Co-Prime Samplers and Arrays
P.P. Vaidyanathan,Piya Pal +1 more
TL;DR: This paper considers the sampling of temporal or spatial wide sense stationary (WSS) signals using a co-prime pair of sparse samplers and shows that the co-array based method for estimating sinusoids in noise offers many advantages over methods based on the use of Chinese remainder theorem and its extensions.
