Signal Processing & Machine Learning

The Signal Processing Division (also fondly referred to as the DSP Division thanks to its penchant for solving problems digitally) works in a variety of areas that involve the manipulation of information-bearing signals. The division comprises both those people who specialise in the transmission of such signals over large distances (Telecommunications) and through complex networks (Network Theory), and those people who are interested in extracting and embedding the information in the signal – whether it be digital data (Digital Communications and Media) or natural-world signals such as speech (Speech Processing) and images (Image Processing).
A visitor looking to find the Signal Processing Division’s DSP Laboratory is encouraged to follow the rich aroma of freshly-brewed filter coffee, the substance that fuels approximately 30 post-graduate researchers in our well-equipped laboratories. Since so much of our research involves the manipulation of information, the main work area is a large computer network running Ubuntu Linux. The division also maintains three smaller laboratories for specialised equipment and hardware development. Five full-time faculty members oversee the research effort.

The activities in the Signals Division can be divided into five primary research areas, each with its own projects and staff members.

Signal Processing Group
Digital Signal Processing GroupWe are a research group within the Department of Electrical and Electronic Engineering concerned with Digital Signal Processing. Yearly we attract numerous postgraduate engineering students studying towards their Masters and PhD degrees. The group has many areas of particular focus and research targeting signal processing of various kinds. These include speech recognition, image processing, broadcasting, network protocols, under-water communication and software defined radio.

Media Lab
The Media Lab
The Media Lab hosts an innovative and fun team of students and staff, working on projects related to data analysis and machine learning.
