About

Ifiok Otung (dubbed Best Lecturer International by Glamorgan University Students’ Union in April 2012) is Professor of Satellite Communications at the University of South Wales (USW, formerly University of Glamorgan). He earned the degrees of BSc (First Class Honours) and MSc in Electronic & Electrical Engineering from the University of Ife Nigeria, and PhD in Satellite Communications from the University of Surrey, UK. Since 1997 he has been at USW where he teaches courses in Satellite, Mobile and Digital Communications and has supervised around 120 postgraduate projects, including MSc and PhD.

Prof Otung is a Chartered Engineer with broad and international experience of research and teaching at various universities in Europe and Africa. He has trained countless students of various nationalities and served as External Examiner of both undergraduate and PhD work at Universities in the UK, Asia and Africa. He has worked as a consultant for several research establishments and run short courses attended by engineers from leading companies and organisations in Europe. He also founded and continues to manage the popular MSc in Mobile and Satellite Communications at USW.

Prof Otung researches in the areas of Mobile & Satellite Communication Systems and Radiowave Propagation where he has over 140 publications and regularly reviews technical articles and textbooks for some of the world’s leading academic publishers. His best known work is the 664-page textbook titled Communication Engineering Principles, ISBN 0 333 77522 8, which is used in leading Engineering Departments around the world, e.g., Oxford, Cambridge, UCL, Surrey, Southampton, Lancaster and Cardiff, to name a few in the UK, and was described by one adopting lecturer in London as “the best book I’ve seen!”.

On 10th February 2014, the IET (Institution of Engineering and Technology) London released Prof Otung’s latest major work, a 520-page textbook titled Digital Communications Principles and Systems which breaks the complex subject of digital communications into its simple parts to give advanced undergraduates, postgraduates and practicing engineers in-depth expertise in the core principles of digital transmission and a complete understanding of the significance and interplay of the design parameters involved in digital communication systems.
