Three techniques are presented: (1) an adaptive compressive sampling GPS correlator that reduces acquisition energy by 4.7x\u201351x in 65 nm CMOS, (2) a beamspace MVDR algorithm that replaces O(N\u00b3) matrix inversion with O(N log N) FFT-based operations, and (3) a gradient-descent-based beam tracker with adaptive step size and update-period control, validated in 16 nm and 28 nm CMOS implementations. Together, runtime adaptation to signal conditions delivers significant energy savings without sacrificing the digital baseband processing performance.\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Adaptation technique for energy-efficient digital baseband processor"}],"uid":"28475","created_gmt":"2026-04-16 18:44:29","changed_gmt":"2026-04-16 18:46:11","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-05-14T13:00:00-04:00","event_time_end":"2026-05-14T15:00:00-04:00","event_time_end_last":"2026-05-14T15:00:00-04:00","gmt_time_start":"2026-05-14 17:00:00","gmt_time_end":"2026-05-14 19:00:00","gmt_time_end_last":"2026-05-14 19:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Online","extras":[],"related_links":[{"url":"https:\/\/gatech.zoom.us\/j\/92270009717","title":"Zoom link"}],"groups":[{"id":"434371","name":"ECE Ph.D. Proposal Oral Exams"}],"categories":[],"keywords":[{"id":"102851","name":"Phd proposal"},{"id":"1808","name":"graduate students"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
