Centre for Telecommunications and Information Engineering








Expertise in telecommunications and information engineering is reflected through leading edge research. There is strong collaboration between Monash University and outside organisations, both in Australia and overseas.






The CTIE networks group are experts in design and control of high speed networks supporting real time applications. Particular expertise within the group includes:

Internet networks, IP version 6, Mobile IP, ATM Networking, Quality of Service, Network Simulation, Performance testing, Network Management, Satellite Links.

The group has a particular focus on working with real networks and maintains a large testbed network within the CTIE laboratories for this purpose. The network includes IP, ATM, Ethernet, wireless mobile, and satellite links and provides network management and analysis capabilities. Research includes leadership of Project 1.1 - Next Generation Internet for the Australian Telecommunications Cooperative Research Centre, a federal government, industry and University initiative. The networks group provided overseer services to the Australian Automotive Exchange Network and has been involved in many other network design projects. They have undertaken a large range of consultancies, up to and including whole of country internets. Networks group staff are also involved in teaching professional short courses as well as undergraduate and postgraduate subjects including ATM Networks, Internet Networking and Telecommunications Performance Analysis.

Extensive DSP research encompasses the areas of telecommunications, robotics, and biomedical and power engineering. Research and teaching utilises the state of the art DSP laboratory established by Texas Instruments. Continued sponsorship by the company ensures that the laboratory remains a leading facility.


CTIE's research expertise builds on more than a decade of video coding and video applications work. This includes work in the early 70's developing one of the first video codecs in collaboration with Siemens (Australia), and contributing to MPEG standarisation , through to the development of one of the first video on demand applications for education
'McIVER' (Multi-campus interactive education resource) and a streaming and distributed video application 'Digital Media Library'.

Current research includes line and video coding, space-time processing in fixed and mobile wireless communications, MPEG-4, subject recognition in video sequences, video restoration, encryption for streaming video, digital watermarking for still images and video, video processing for unmanned air vehicles (UAV), and audio and video on demand. A audio on demand service developed for lecture recall by students of the University can be sampled on the Monash library webpages.

Research to push the boundaries of communication capacity includes areas of ultra-broadband (up to and possibly higher than 10 Tera-bps) communication transmission and networks including lightwave generation and modulation techniques, transmission properties of optical guided media, optical amplification and detection techniques, especially novel modelling techniques in frequency domain for nonlinear operating-regime of optical systems and networks, optical transport network modelling for DWDM optically amplified transport networks, optical packet switched transmission and networking design techniques, quantum communications over optical fibre transmission systems and networks, and photonic Signal Processing for All-Optical Communications Systems and Networks.

The Optical Communications Laboratory has recently been updated with the donation of Long-Reach Ultra-High Capacity optical equipment by Siemens

Advances in audio electronics are seriously challenging linear amplifiers. Research in this area has caught the attention of a number of companies in the entertainment business for its advances in audio amplifiers, electrostatic loudspeakers and low-frequency enclosures.

Leading edge research is conducted in areas of national and international significance. Collaboration includes work with the Australian Telecommunications Cooperative Research Centre, with the Country Fire Authority and other community, government and industry groups.

Research areas includes steerable antenna arrays, propogation, microwave, antennas and propagation for Third Generation Mobility, ionospheric structure and propgation, HF Radars, and Over-the-horizon radar.

An anechoic chamber assists with experimentation and RF design.

Electromagnetism has a fundamental effect on modern telecommunications systems. Research is conducted in theoretical analysis and the effects in transmission lines and telecommunications systems particularly wireless, and the effect on biological systems.

Successful research can lead to safer and more efficient communications environments, for instance on a bushfire front where the intense heat and radiation will cause electromagnetic interference with the communication systems used by firefighters.

An EMC laboratory is currently being established, and research conducted in collaboration with EMC experts in Europe, particularly Hungary and Sweden.

OMNET++ is currently the preferred tool for simulating networks, with the IPv6Suite developed onsite.
IPv6Suite is an open source OMNeT++ model suite for accurate simulation of IPv6 protocols and networks.
For simulation work, there is The "Pizzeria": CTIE's Linux Cluster containing 9 dual cpu Sun pizza boxes. In addition there is access to VPAC and APAC, as well as other clusters.

The facilities within the Centre are being constantly changed and updated almost on a monthly basis. The list below should be treated as a representative only.

Digital audio/video compression laboratory (Room 113, Building 31)
