Telecommunications and Signal Processing

Our staff have strong records in creating commercial outcomes from fundamental research in telecommunications and signal processing. These include:
  • algorithms and their efficient implementation for Orthogonal Frequency Division Multiplexed (OFDM) radio and photonic systems. Optical OFDM (oOFDM)  is being commercialised by Ofidium Pty Ltd,  and has recently had a large investment from the Trans Tasman Commercialisation Fund (TTCF) -- a new Melbourne-based $30 million seed investment fund, supported in Victoria through the Victorian Government. The TTCF, designed to help the early-stage commercialisation of opportunities developed at universities across South Eastern Australasia, including Monash University. This is the first investment by TTCF into Victorian university research.
  • internet protocols for mobile wireless systems
  • simulation software to aid the design of photonic links
  • optimization tools for photonic networks  MOCSS2004
  • photonic local area network technologies  
  • Radio-Frequency IDentification (RFID) technology
We work closely with global and local industry to ensure the relevance of our research. We also conduct innovative research in emerging areas of telecommunications theory and practice. This has led to awards for innovation such as the Peter Doherty Prize for Innovation for our work combining OFDM and photonics, for example, and many postdeadline papers in top international conferences. Our telecommunications research laboratories are equipped with the latest test and measurement equipment and fully-operational commercial systems, including:
  • Siemens 16 x 10 Gbit/s 600-km optical communications link designed for Melbourne-Sydney
  • Arbitrary waveform signal generation to 20 Gsamples/s x2 channels (to test theoretical waveforms in real communications and radar systems)
  • Signal capture to 50 GSamples/s x4 channels (to examine physical waveforms and apply advanced signal processing to them)
  • Optical Spectrum Analysis (20Mhz resolution, 0.06 nm resolution)
  • 800-km optical fiber test bed designed particularly to prototype optical systems using digital signal processing for dispersion compensation
  • Fully-equipped optical communications laboratory including 40 Gbit/s signal generation, detection and Bit Error Rate (BER) counting
  • RF component characterisation to 67 GHz
  • RF anechoic and screened chambers for antenna development and characterisation
  • Computer clusters for IP protocol development and performance testing
  • Advanced simulation software for photonic and electromagnetic design
  • Grid computing for large-scale simulations
This equipment allows us to rapidly prototype our ideas, speeding the path to international publications and commercialisation. Our PhDs go on to use their expertise in global high-tech companies based in Australia and the world. For further details of opportunities at Monash, please contact:
