Communications, Signal Processing & Networking

Digital communications have been the most transformative technology to impact society in the past 50 years. Increasingly, it’s impossible to imagine life without email, smartphones, video calls, social media, online gaming or instant access to a wealth of multimedia content.

The School of Engineering Science’s Communications, Signal Processing and Networking (CSPAN) group studies the science and engineering that makes all this possible. This ranges from signal and data acquisition, through sampling, information extraction, coding, modulation, transmission, learning and understanding and even the interaction between humans and signals.

Featuring a dynamic research portfolio managed by our world-renowned faculty, CSPAN attracts outstanding students from around the world. Our alumni have won local, national and international accolades and are highly sought after by industry and academia.
