Broadcasting 3D Audio: Recording, Transmission, and Playback. With the current state of the art, a performance at the Sydney Opera House cannot be recorded and broadcast such that you can listen to it as if you are in the best seat of the house. The goal of our project is to develop the ultimate form of multi-channel audio broadcasting to create this experience. We will develop and implement effective systems for recording, broadcasting and playback of 3D audio in three different scenarios: indi ....Broadcasting 3D Audio: Recording, Transmission, and Playback. With the current state of the art, a performance at the Sydney Opera House cannot be recorded and broadcast such that you can listen to it as if you are in the best seat of the house. The goal of our project is to develop the ultimate form of multi-channel audio broadcasting to create this experience. We will develop and implement effective systems for recording, broadcasting and playback of 3D audio in three different scenarios: individual headphone reproduction; small loudspeaker array reproduction; and large loudspeaker array reproduction. We will create optimal recording techniques and broadcasting software for each of these playback techniques.Read moreRead less
Model-Reduction Techniques for Control, Communication and Circuits. Model reduction is an important area of study in the analysis and design of dynamical systems. Its objective is to obtain a low-order model given a high-order system model such that the low-order model closely approximates the input-output behaviour of the original high-order system. Although theory and application of model reduction is well developed, there are many unresolved issues such as efficient model reduction techniq ....Model-Reduction Techniques for Control, Communication and Circuits. Model reduction is an important area of study in the analysis and design of dynamical systems. Its objective is to obtain a low-order model given a high-order system model such that the low-order model closely approximates the input-output behaviour of the original high-order system. Although theory and application of model reduction is well developed, there are many unresolved issues such as efficient model reduction techniques for large-scale circuit simulation and communication applications, frequency-weighted model reduction techniques for controller-design applications, and error bounds for the reduction techniques. The project aims to address these issues.Read moreRead less

Demonstrating Advantages of Smart Antennas in Indoor Wireless Communications Systems. The performance of indoor wireless communications systems is adversely affected by multi-path signal propagation. When the received signal drops below a certain level, the usual practice is that the receiving station requests the transmitting device to increase its output power. An adverse effect of this action is a reduced life of battery of a portable transceiver, more power being radiating towards users and ....Demonstrating Advantages of Smart Antennas in Indoor Wireless Communications Systems. The performance of indoor wireless communications systems is adversely affected by multi-path signal propagation. When the received signal drops below a certain level, the usual practice is that the receiving station requests the transmitting device to increase its output power. An adverse effect of this action is a reduced life of battery of a portable transceiver, more power being radiating towards users and an increase of interference. The aim of this project is to demonstrate an alternative method of maintaining good quality communication link. The proposed method employs a smart antenna system to mitigate adverse effects of multi-path and interference.Read moreRead less
