A main limiting factor in supplying future broadband communications is overcoming signal dispersion in the transmission channel. Recent preliminary collaboration by the chief investigators has uncovered a novel approach to this problem based on powerful mathematical lattice theory. The techniques have potential to significantly increase bandwidth and reliability compared to current technologies. This project will use lattice theory to propose, develop, analyse and test new data transmission techniques including joint coding, modulation and equalisation. The research will include theoretical analysis and hardware implementation. The overall aim is to dramatically improve reliability and throughput of data communication systems.Read moreRead less

Robust feature extraction for automatic speech recognition. Speech is perhaps the most natural and efficient mode of communication for humans. Therefore, it has always been a dream for many people to communicate with machines via speech. Significant advances have been made in the last five decades in the area of automatic speech recognition. Though the currently available speech recognisers work reasonably well in noise-free office environments, their performance deteriorates drastically when th ....Robust feature extraction for automatic speech recognition. Speech is perhaps the most natural and efficient mode of communication for humans. Therefore, it has always been a dream for many people to communicate with machines via speech. Significant advances have been made in the last five decades in the area of automatic speech recognition. Though the currently available speech recognisers work reasonably well in noise-free office environments, their performance deteriorates drastically when they are deployed in real-life situations due to the presence of background noise and other distortions. The problem of robust speech recognition will be researched in this project. Read moreRead less
Electromagnetic field strength simulator (ELMO) for RF hazard assessment. There is significant community fear related to exposure to mobile telephone radiation. The computer program ELMO will be designed to accept information about all RF transmitters in the vicinity of cellular telephone towers from an existing database, and to calculate the total field strength. This will allow hazard assessment for both RF technicians working on the tower and adjacent residents.
Specifications, Proofs and Animations for Cryptographic Protocols. Cryptographic protocols are fundamental security tools for electronic communications. Despite years of intensive research it remains difficult to obtain high confidence in the security of almost any new protocol. Research in the computer security community has emphasised formal specifications and state based searching, while the cryptographic community has concentrated instead on complexity theoretic proofs. This project will un ....Specifications, Proofs and Animations for Cryptographic Protocols. Cryptographic protocols are fundamental security tools for electronic communications. Despite years of intensive research it remains difficult to obtain high confidence in the security of almost any new protocol. Research in the computer security community has emphasised formal specifications and state based searching, while the cryptographic community has concentrated instead on complexity theoretic proofs. This project will unify these two approaches for the first time by formally specifying and animating the very models used in cryptographic proofs. The result will be proofs that are uniquely accessible to practioners combined with increased confidence that the proofs are both correct and relevant.Read moreRead less

Fixed and variable-length segment vocoders for very low bitrate speech coding. Reliable and secure voice communication is an important aspect of military and defence operations. In order to reduce the possibility of interception, low power transmitters are normally used for radio communications, where the bandwidth is often very low.

Reliable and secure voice communication is an important aspect of military and defence operations. In order to reduce the possibility of interception, low power transmitters are normally used for radio communications, where the bandwidth is often very low. Military voice communication, therefore, requires the coding of speech at very low bitrates. Our research proposal aims to develop speech coders that can operate at lower bitrates and reproduce speech of high quality and intelligibility. This is highly beneficial to the defence forces of Australia as it will permit the use of high-grade encryption technology to improve the security of transmission.Read moreRead less
