Proceedings ArticleDOI
Distributed SNR estimation using constant modulus signaling over Gaussian multiple-access channels
TL;DR: A sensor network is used for distributed SNR estimation and performance evaluated using the asymptotic variance of the estimators shows that the computationally simple estimators have the same asymPTotic performance as the minimum-variance estimators.
Proceedings ArticleDOI
Tracking the Path Shape Qualities of Human Motion
TL;DR: A probabilistic generative model for extracting intended path shape qualities of an object moving under human control in real time, which is successfully embedded in a hybrid physical-digital interface where the position of an illuminated ball, sensed by a low-cost video camera array, triggers multimodal feedback in a mediated learning environment.
Proceedings ArticleDOI
DNA sequence alignment using the matching pursuit decomposition
Lakshminarayan Ravichandran,Antonia Papandreou-Suppappola,Andreas Spanias,Zoé Lacroix,Christophe Legendre +4 more
TL;DR: A time-frequency based alignment technique using the matching pursuit decomposition method and a mapping algorithm is proposed to identify local and global alignments more efficiently and with greater precision than existing methods.
Proceedings ArticleDOI
Fast frequency domain implementation of a block IIR filter with application
TL;DR: The frequency-domain implementation of the recently proposed time domain optimal block adaptive recursive algorithm (OBAR) was used successfully for high-order system identification, adaptive noise cancellation, and pole-zero prediction.
An Interdisciplinary Arts And Engineering Initiative For Experiential Multimedia
TL;DR: The Arts, Media and Engineering (AME) graduate education and research program at Arizona State University as mentioned in this paper is a hybrid education and training program for arts and media education and education, which allows students to combine extensive training in their chosen discipline offered through their home department with hybrid engineering-arts-sciences training offered through AME.
