Objectives

To research the efficient, secure and reliable transmission of speech, image, video and other data sources over various communication channels, with special emphasis on mobile channels. Novel techniques in the following areas are to be investigated:

Digital communications
Data and computer communications
Speech, Image and Signal Processing 
Digital Multimedia
Parallel computer architectures for signal processing
Video coding
Video conferencing
Multimedia networking and Security
Wireless multimedia
Cryptography
Error-control coding
Source coding

In addition, various mobile and wireless channels are to be characterised, especially in the Maltese environment.

Also of special interest to the Department is research in:

Real Time Operating Systems for the 8051 microcontroller.
Embedded Systems
Speech synthesis and recognition for the Maltese language


Current Research

Digital video transmission over wireless access networks
Variable-length error-correcing codes
Soft decision decoding for block codes
Synthesis and recognition of Maltese speech
Multimedia indexing
