Extremes of Random Coding Error Exponents

Speaker: Albert Guillén i Fàbregas, University of Cambridge

Talk Title: Extremes of Random Coding Error Exponents

Abstract: In this talk, we will briefly review Gallager's random coding achievability proof. We will show that Gallager's random coding error exponent of an arbitrary binary-input memoryless symmetric channel is upper-bounded by that of the binary erasure channel and lower-bounded by that of the binary-symmetric channel of the same capacity. We will illustrate how the result can be applied to find the extremes of the channel dispersion for the aforementioned class of channels.

Biography: Albert Guillén i Fàbregas received the Telecommunication Engineering Degree and the Electronics Engineering Degree from Universitat Politècnica de Catalunya , Barcelona, Catalunya, Spain, and the Politecnico di Torino , Torino, Italy, respectively, both in 1999, and the Ph.D. in Communication Systems from Ecole Polytechnique Fédérale de Lausanne (EPFL), Lausanne, Switzerland, in 2004.

From August 1998 to March 1999, he conducted his Final Research Project at the New Jersey Institute of Technology , Newark, NJ. He was with Telecom Italia Labs, Italy, from November 1999 to June 2000. From September 2000 to May 2001, he was with the European Space Agency (ESA), The Netherlands. During his doctoral studies, from 2001 to 2004, he was a Research and Teaching assistant at Institut Eurécom , France. From June 2003 to July 2004 he was a visiting scholar at EPFL. Since September 2004 until December 2006 he was a Research Fellow at the Institute for Telecommunications Research , University of South Australia , Australia. From January 2007 he has been a Lecturer at the Department of Engineering , University of Cambridge , United Kingdom. He is also a Fellow of Trinity Hall . He held visiting appointments at Ecole Nationale Supérieure des Télécommunications , Paris, France (June-July 2005 and June 2006),Universitat Pompeu Fabra , Barcelona, Spain (September 2008), at the Institute for Telecommunications Research , University of South Australia , Mawson Lakes, Australia (December 2008, June-July 2010) and Texas A&M Univeristy at Qatar (May 2010). His specific research interests are in the area of communication theory, information theory, coding theory, digital modulation and signal processing techniques, particularly with wireless terrestrial and satellite applications.

Dr. Guillén i Fàbregas received the Starting Grant from the European Research Council , the Young Authors Award of the 2004 European Signal Processing Conference EUSIPCO 2004, Vienna, Austria, the 2004 Nokia Best Doctoral Thesis Award in Mobile Internet and 3rd Generation Mobile Solutions from the Spanish Institution of Telecommunications Engineers , and a pre-doctoral Research Fellowship of the Spanish Ministry of Education to join ESA. He is also a Senior Member of IEEE (Information Theory and Communications Societies ), of theARC Communications Research Network (ACoRN), and a Junior member of the Isaac Newton Institute for Mathematical Sciences . Since November 2007, he has been an Editor of the IEEE Transactions on Wireless Communications
