DESCRIPTION:Prof. Frank Kschischang\, University of Toronto - Invited by P
 rof. Michael Gastpar\nAbstract We describe staircase codes\, a new class o
 f error-control codes suitable for high-speed optical communications.  On
 e sample design\, targeted at 100Gb/s optical transport networks\, yields 
 an ITU-T G.709-compatible staircase code with rate R=239/255 for which FPG
 A-based simulation results exhibit a net coding gain (NCG) of 9.41 dB at a
 n output error rate of 10^{-15}\, an improvement of 0.42 dB relative to th
 e best code from the ITU-T G.975.1 recommendation.   An error floor anal
 ysis shows that this code has an error floor below 10^{-20}.  These codes
  can be exploited in higher-order modulation schemes incorporating signal 
 shaping\, to achieve reliable communication near the estimated capacity of
  fiber channels.  For example\, one design yields a practically achievabl
 e spectral efficiency within 0.62 bits/s/Hz of the estimated capacity of a
  long-haul fiber channel having a length of 2000 km. (Joint work with Benj
 amin P. Smith.) Biography Frank R. Kschischang is a Professor of Electrica
 l and Computer Engineering at the University of Toronto\, where he holds t
 he Tier I Canada Research Chair in Communication Algorithms. His research 
 interests are focused primarily on the area of channel coding techniques\,
  applied to wireline\, wireless and optical communication systems and netw
 orks. In 2010 he was awarded the Killam Research Fellowship by the Canada 
 Council for the Arts. Jointly with Ralf Koetter he received the 2010 Commu
 nications Society and Information Theory Society Joint Paper Award. He is 
 a Fellow of IEEE\, and served as the 2010 President of the IEEE Informatio
 n Theory Society.
