Title:<\/strong> DESIGN OF THROUGHPUT-EFFICIENT HARQ PROTOCOLS<\/p>\n\n\n\n

Speaker:<\/strong> Leszek Szczecinski, Professor, INRS, Montreal<\/p>\n\n\n\n

ABSTRACT:<\/strong> In this presentation, we are interested in increasing the
\nthroughput of the physical layer (PHY) when the coded information is
\ntransmitted using equal-length channel blocs which are subject to
\nindependent fading. We consider adaptive modulation and coding (AMC)
\nand hybrid ARQ (HARQ) and analyse their interaction; in particular, we
\nexplain why the conventional HARQ which reserves the channel blocks to
\ncarry the coded versions of the same information packet, is unable to
\nincrease the throughput in the range of high-SNR. We then discuss
\ndegrees of freedom in the design of HARQ with the main focus being on
\nthe joint encoding\/decoding of many packets and on the related design
\nissues. We show various solutions which lead us to a simple two-layer
\nencoding where, first, the binary packets compressed, and next, the
\nresults are passed to the conventional channel encoder. This approach
\nallows us to use off-the-shelf decoders, and the coding rates can be
\ndeduced from the empirical decoding curves.<\/p>\n\n\n\n

Speaker Bio:<\/strong> Leszek Szczecinski is Professor at INRS, University of Quebec,
\nCanada. He obtained M.Eng. degree from the Technical University of
\nWarsaw in 1992, and Ph.D. from INRS-Telecommunications, Montreal in
\n1997. From 1998 to 2001, he held position of Assistant Professor at
\nthe Department of Electrical Engineering, University of Chile. In
\n2009-2010, as a Marie Curie Research Fellow, he was with CNRS, L2S,
\nGif-sur-Yvette, France. His research interests are in the area of
\ncommunication theory, modulation and coding, ARQ, wireless
\ncommunications, and digital signal processing. He coauthored a book
