       Senior Lecturer in Signal Processing and Telecommunications for Mobile Systems Architecture (MSA)

 

Appointed to current post in February 1998.
From October 1979 until January 1998,
Barry was a lecturer in the Department of Electrical Engineering & Electronics, Liverpool University, UK.

 

 

 

 

 

Current research interests:

  • Voice processing for high quality ‘voice-over-wireless LAN’ (VoWLAN) over converged enterprise networks
  • Coding of speech for mobile communications
  • Computer network technology for distance learning
  • Speech technology (speech coding, analysis and synthesis)
  • Implementation of speech processing algorithms on an asynchronous DSP core
  • Digital signal processing applied to the acoustical analysis of musical performance
  • Digital signal processing applied to the analysis am monitoring of biomedical signals (pulmonary sounds analysis)

I have held about 25 research grants, including 5 EPSRC and 2 EU grants including a European "concerted action”.

I supervised 29 successful Ph.D. projects, and had long term involvement with a number of communications companies including BT.

I have published 1 book, 2 book chapters, 27 journal papers, 40 international conference papers, 20 colloquium papers, 9 abstracts, 3 articles and have been responsible for four patents held by BT.

I have extensive teaching and administrational experience including that of being instigator and Director of an M.Sc.(Eng.) Course in Telecommunications and Micro-electronic Systems. I also set up and ran a short course for industry on "Digital Signal Processing".

I have been a member and chairman of the IEE E10 "Circuits & Systems" professional group committee, a member of IEE Divisional Board, Premiums Committees, and other professional groups.
