For many DSP applications (packet data traffic, geophysics, medical imaging, and astronomy, for example), resampling is used to convert data between uniform and non-uniform grids, which eases both the acquisition process and the data analysis. \u0026nbsp;This talk presents new resampling algorithms that use the Fast Fourier Transform (FFT) and Fast Multipole Method (FMM) to resample between uniform and non-uniform sampling grids through sinc interpolation. These algorithms are based on several results from structured linear algebra, and yield highly accurate resampling with FFT-like asymptotic complexity. \u0026nbsp;We demonstrate the potential utility of these algorithms by considering the computational savings they could offer to level-crossing ADCs.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ESpeaker Bio:\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EChris Turnes received his B.S. in electrical engeering from the University of Maryland College Park in 2007 and his M.S. from Georgia Tech in 2010. \u0026nbsp;He is currently a Ph.D. candidate in electrical engineering at Georgia Tech, under the direction of Justin Romberg. \u0026nbsp;His research interests are efficient algorithms for structured linear algebra and their applications to signal processing.\u003C\/p\u003E\u003Cp\u003EChris leads an interesting personal life, as well. \u0026nbsp;In high school, his superlative was given as simply \u0022Most.\u0022 \u0026nbsp;He is the co-creator of NBC\u0027s \u0022Grads,\u0022 and is credited as one of the authors of the original Port Huron statement (not the compromised second draft). \u0026nbsp;In a tribute to his musical prowess, he was once chosen to host the Grammys, giving every award to Cory Hart. \u0026nbsp;He enjoys reading, and has many leather-bound books that he reads in his condo (which smells of rich mahogany). \u0026nbsp;He is said to be the life of parties he\u0027s never attended, and it is rumored that the film \u0022The Bourne Ultimatum\u0022 is loosely based on his life.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003E\u003Cem\u003ESuperfast algorithms for digital resampling between uniform and non-uniform grids\u003C\/em\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cem\u003E\u003Cbr \/\u003E\u003C\/em\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cem\u003E\u003Cbr \/\u003E\u003C\/em\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cem\u003E\u003Cbr \/\u003E\u003C\/em\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cem\u003E\u003Cbr \/\u003E\u003C\/em\u003E\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":"","uid":"27842","created_gmt":"2014-01-07 18:54:00","changed_gmt":"2017-04-13 21:23:34","author":"Ashlee Gardner","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2014-01-24T14:00:00-05:00","event_time_end":"2014-01-24T15:00:00-05:00","event_time_end_last":"2014-01-24T15:00:00-05:00","gmt_time_start":"2014-01-24 19:00:00","gmt_time_end":"2014-01-24 20:00:00","gmt_time_end_last":"2014-01-24 20:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1255","name":"School of Electrical and Computer Engineering"}],"categories":[],"keywords":[],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[{"id":"78751","name":"Undergraduate students"},{"id":"78761","name":"Faculty\/Staff"},{"id":"174045","name":"Graduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EAhmad Beirami\u003C\/p\u003E\u003Cp\u003E\u003Ca href=\u0022mailto:beirami@ece.gatech.edu\u0022\u003Ebeirami@ece.gatech.edu\u003C\/a\u003E\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
