Dr. Haccoun is an internationally recognized authority in the theory and applications of error control coding using convolutional codes. His outstanding contributions on powerful codes and decoding techniques have substantially impacted the development of very reliable wire-less communication systems. In particular, his internationally acclaimed work on high-rate punctured convolutional codes has contributed to fundamental simplifications in the development of variable rate communications. He co-invented a class of powerful doubly orthogonal convolutional codes that substantially simplify the best known iterative decoding techniques. He received numerous national and international awards and honours(e.g.: .IEEE-VTS Awards : Oustanding Services Awards 2007&2015; Distinguished Lecturer VTS 2011-2013; Stuart Meyer Memorial Award-2018, Major VTS Award ; IEEE Canada  R.G. Fessenden Medal) . His books have been widely used for academic and professional education.
