Millimeter-wave bands provide sufficient spectral resource and avoid cross-tier interference with existing low-frequency wireless services in a heterogeneous network. However, coordination over millimeter-wave small cells for combating interference, providing line-of-sight links, and improving system efficiency has stringent requirements on synchronizations and backhaul capacity. As a result, current standards and approaches for the coordination of low-frequency cells based on distributed digital processing can barely apply on millimeter-wave small cells. This work theoretically and experimentally explores new directions of inter-cell interference cancellation and coordinated multi-point transmissions for coordination over millimeter-wave small cells. Different from conventional approaches, the millimeter-wave coordination mechanisms studied in this research are inherent from a fiber-wireless architecture that enables optical processing for millimeter-wave generation, distribution, synchronization, and centralized coordination. Based on the supportive results derived from the preliminary study of the mechanisms, we propose the methods of cooperative multiple-input multiple-output and network-wide coordination based on optical processing and fiber-wireless centralization for multi-cell and multi-user coordination over millimeter-wave small cells. The proposed methods utilize centralized resource and local high-capacity fiber links and are expected to provide transparency and global coherency for efficient coordination and seamless integration with future heterogeneous networks.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"ECE Proposal Oral Exam"}],"uid":"28475","created_gmt":"2016-05-03 16:50:54","changed_gmt":"2016-10-08 02:17:40","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2016-05-10T15:00:00-04:00","event_time_end":"2016-05-10T15:00:00-04:00","event_time_end_last":"2016-05-10T15:00:00-04:00","gmt_time_start":"2016-05-10 19:00:00","gmt_time_end":"2016-05-10 19:00:00","gmt_time_end_last":"2016-05-10 19:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"434371","name":"ECE Ph.D. Proposal Oral Exams"}],"categories":[],"keywords":[{"id":"1808","name":"graduate students"},{"id":"102851","name":"Phd proposal"}],"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":""}}}
