Modern communication systems, which need to be connected everywhere and at all times, require each device to be a small size, and require stringent standards for the RF systems. From a transmitter perspective, in face of explosive increase in data rates requires high speed complex modulation schemes with high spectral efficiency and large peak-to-average power ratios (PAPRs), such as high-order quadrature amplitude modulations (QAMs) and orthogonal frequency-division multiplexing (OFDM). From a receiver perspective, massive RF applications lead to a crowed spectrum, making receivers susceptible to mutual interference. Hence, along with cost and power consumption, interference robustness is becoming a major concern for the radios targeting these applications. This proposal focuses on the design of digital power amplifier and transceiver, which can be one of solutions for these requirements.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Hybrid Digital PA and Bidirectional Digital Transceiver Circuits in Silicon"}],"uid":"28475","created_gmt":"2021-11-03 21:58:11","changed_gmt":"2021-11-03 21:58:11","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2021-11-12T08:30:00-05:00","event_time_end":"2021-11-12T10:30:00-05:00","event_time_end_last":"2021-11-12T10:30:00-05:00","gmt_time_start":"2021-11-12 13:30:00","gmt_time_end":"2021-11-12 15:30:00","gmt_time_end_last":"2021-11-12 15:30:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"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":""}}}
