Title:<\/strong> DESIGN OF PERMUTATION-BASED SPARSE CODE MULTIPLE ACCESS SYSTEM<\/p>\n\n\n\n

Speaker:<\/strong> Dr. Michel Kulhandjian, Research Scientist, School of Electrical Engineering and Computer Science, University of Ottawa<\/p>\n\n\n\n

ABSTRACT:<\/strong> We consider the problem of designing a sparse code multiple
\naccess (SCMA) codebook that is based on permutation. Conventional SCMA
\nis a multidimensional codebook-based non-orthogonal spreading
\ntechnique, in which each layer of incoming bits is directly mapped to
\nmultidimensional codewords which have nonzero entries on the same
\nresources. In this paper, unlike the traditional SCMA scheme, the data
\nbits to be transmitted determine the nonzero entry locations based on
\nthe permutation. The proposed SCMA codebooks are converted to a
\nmultiuser code-division multiple-access (CDMA) detection system before
\napplying an iterative decoder. The complexity of the proposed
\niterative decoder is lower in comparison to exponential message
\npassing algorithm (MPA) and outperforms in terms of bit-error-rate
\n(BER).<\/p>\n\n\n\n

Speaker bio:<\/strong> Michel K. Kulhandjian is a Research Scientist in the School of
\nElectrical Engineering and Computer Science at the University of
\nOttawa. His currently working on investigating new encoding and
\ndecoding schemes for Sparse Code Multiple Access (SCMA) in
\ncollaboration with Prof. Claude D\u2019amours. He is also employed as an
\nembedded software designer at Harris Corporation in Ottawa, where he
\nis working on designing and developing software platform for
\nAir-to-Ground, Ground-to-Ground IP-based ATM voice communication
\nsystems. He received his M.S. and Ph.D. degrees in Electrical Engineer
\nfrom the State University of New York at Buffalo in 2007 and 2012,
\nrespectively. He had previously received his B.S. degree in
\nElectronics Engineering and Computer Science (Minor), with \u201cSumma Cum
\nLaude\u201d from the American University in Cairo (AUC) in 2005. He was
\nemployed at Alcatel-Lucent, in Ottawa, Ontario, in 2012, to conduct
\nR&D in the area of Next Generation Cloud Based Wireless Network
\nArchitecture. In the same year he was appointed as a Research
\nAssociate at EION Inc. He received Natural Science and Engineering
\nResearch Council of Canada (NSERC) Industrial R&D Fellowship (IRDF) to
\nresearch on reliability and enhancement and performance optimization
\nof broadband wireless networks.<\/p>\n\n\n\n

His research interests include wireless multiple access
\ncommunications, sparse code multiple access (SCMA), signature waveform
\ndesign for overloaded code-division multiplexing applications,
\nadaptive multiuser detection, statistical signal processing, covert
\ncommunications, spread-spectrum steganography and steganalysis. Dr.
\nKulhandjian serves as a member of Technical Program Committee (TPC) of
\nIEEE International Conference on Wireless and Mobile Computing and
\nCommunications (WiMob2017), IEEE Globecom 2017, IEEE International
\nConference on Communications (ICC2018-CQRM, ICC2016-CQRM), IEEE
\nVehicular Technology Conference (VTC2016-Spring, VTC2015-Fall,
\nVTC2013-Fall, and VTC2012-Fall).<\/p>\n","protected":false},"excerpt":{"rendered":"
