Information × Registration Number 0206U000161, 0103U000474 , R & D reports Title Terrestrial Cellular and Satellite Repeater Communications System. popup.stage_title Head Bunin S.G, Registration Date 17-01-2006 Organization Research Institute of Telecommunications National technical university of Ukraine "KPI" popup.description2 The aim of the work is a solution of scientific-engineering problems for creation of telecommunications system based on packet switched terrestrial cellular and satellite repeaters having high frequency utilization and overloading tolerance.Actuality of the work is based on exclusive usage of packet switching in wideband collective channels instead of wide-spread circuit switching of narrow band telephony channels.An architecture of terrestrial cellular networks has been designed as well as new variants of topology, tipes of repeaters, modulation modes, procedure and structural methods to increase the throughput and overload tolerance, multiple access protocols and its modeling for analyses, methods of an adaptive control also has been designed.An architecture of the Low Earth Orbit satellite network space segment, high efficiency multiple access protocols to satellite repeaters and models for their analyses and best parameters finding have been created.A series of investigations as to the usage of wideband signals have been provided.
