S-UTD-CH model can be used for fast and more accurate field prediction for multiple diffractions in transition zone. An extensive simulation results for comparison of UTD based algorithms with respect to the computation time and accuracy was provided.</dc:description><dc:publisher>IEEE COMPUTER SOC</dc:publisher><dc:date>2012</dc:date><dc:type>Conference Object</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/bayburt/14501</dc:identifier><dc:identifier>978-1-4673-0667-6</dc:identifier><dc:identifier>978-1-4673-0666-9</dc:identifier><dc:identifier>2381-5523</dc:identifier><dc:language>en</dc:language><dc:relation>2012 IEEE ASIA-PACIFIC CONFERENCE ON ANTENNAS AND PROPAGATION (APCAP)</dc:relation><dc:rights>info:eu-repo/semantics/closedAccess</dc:rights><dc:type>info:eu-repo/semantics/conferenceObject</dc:type><dc:identifier>https://bayburt-rdlopen.rawdatalibrary.net/tr/items/bayburt/14501</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
