Bandwidth Utilisation for volume-to-volume UWB MIMO Communications

Aubrey Timothy; Aboura Khalid (IEEE, 2008)

Previous studies have investigated communications between regions of space and have considered the effect of antenna volume in determining the theoretical capacity of multiple-input multiple-output (MIMO) communications ...
A CME Based Channel Estimation Approach for MIMO-OFDM Systems

Lu Zhen; Kadi Anthony; Aubrey Timothy (IEEE Press, 2009)

A pilot-assisted, conditional model-order estimation (CME) based channel estimation algorithm is presented. The algorithm is proposed for MIMO-OFDM systems and can detect both channel frequency responses and number of ...
Differential unitary space-time superset modulation

Smith David; Aubrey Timothy (Lawrence Erlbaum Association, 2007)
Differential Unity space-time Superset Modulation

Smith David; Aubrey Timothy (Federazione Italiana Elettrotecnica, Elettronica, Automazione, Informatica e Telecomunicazioni, 2005)

A simple framework is presented for transmission of constellation supersets, starting from a consideration of differential diagonal unitary space-time modulation (DUSTM), called DUST superset modulation (DUSTSM). The need ...
Evaluation of a magnetic near field scanner

Smart Kenneth; Aubrey Timothy (IEEE, 2009)

Traditionally, the measurement of antenna performance often required significant capital outlay on anechoic test chambers and associated test equipment. A novel device manufactured by Canadian company Emscan that can perform ...
A generalised (M,NR) MIMO Rayleigh channel model for non-isotropic scatterer distributions.

Abhayapala Thushara; Smith David; Aubrey Timothy (National Committee for Radio Science, 2004)

This paper extends a recently proposed space-time model for Rayleigh fading to include an arbitrary transmit antenna configuration of any shape and size transmitting simultaneously in a multiple-input multiple-output ...
Generalised space-time modelling of the MIMO channel applied to analysing and optimising transmit antenna configurations

Smith David; Aubrey Timothy (The Institute of Electrical and Electronic Engineers Inc (IEEE), 2003)

For the purposes of macroscopic system design a space-time Rayleigh fading multiple-input multiple-output (MIMO) radio channel is modelled for an arbitrary transmit antenna configuration of three to six transmit antennas. ...
A hybrid CME-LS channel estimation approach for broadband MIMO-OFDM systems

Lu Zhen; Kadi Anthony; Aubrey Timothy (IEEE, 2009)

A channel estimation approach yielding both channel gains and the number of multi-paths is presented. The algorithm is based on a variation of conditional model order estimation (CME), and is proposed for MIMO-OFDM systems. ...
Performance degradation of differential space-time modulation in fast frequency flat fading Rayleigh MIMO channels

Smith David; Aubrey Timothy (Institute of Electrical and Electronics Engineers, 2003)

The performance degradation of differential unitary space-time modulation of any data rate, R, due to time selectivity is quantified for any number of transmit antennas, M, for fast frequency flat fading Rayleigh ...
Towards an Understanding of Collaboration in Teaching Technology Subjects in an Amalgamated Faculty of Engineering and Information Technology

Lawrence Elaine; Loke Lian; Raban Ryszard; Brookes Wayne; Aubrey Timothy (IEEE Computer Society Conference Publications, 2009)

The paper sets out a collaborative approach for teaching technology subjects. It Illustrates the benefits of this approach over the single academic owning a particular subject. The paper presents preliminary findings from ...
Who leaves and when do they go? Retention and attrition in engineering education

Godfrey Elizabeth; Aubrey Timothy; Crosthwaite Caroline; King Robin (Stipes Publishing LLC, 2010)

At a time of high demand for engineering graduates, the mean graduation completion rate of engineering undergraduates in Australia has been identified as approximately 54% (with considerable variation across institutions ...
Who leaves and who stays? Retention and attrition in Engineering Education

Godfrey Elizabeth; Aubrey Timothy; King Robin (The Higher Education Academy Engineering Subject Centre, 2010)

At a time of high demand for engineering graduates, the mean graduation completion rate of engineering undergraduates in Australia has been identified as approximately 54% (with considerable variation across institutions ...
