"Perceptions in C" is a submission for the ICAD2004 Concert of Sonifications and was composed as a first experiment by us in the field of converting data to music. Our principle objective was to see if the ECG data (or part thereof) could be made at all "listenable" from a musical standpoint. Central to the data processing approach was the use of a colour note organ to directly interpret the pl...

MIMO techniques implemented through STBC, is a highly viable and attractive option for outdoor mobile networks. This paper presents a measurement campaign aimed at characterising the outdoor MIMO channels in the 2GHz UMTS band. Initial results comparing the channel properties and post-processing analysis for STBC schemes are also included.

Joint signal representations (JSRs) of arbitrary variables generalize time-frequency representations (TFRs) to a much broader class of nonstationary signal characteristics. Two main distributional approaches to JSRs of arbitrary variables have been proposed by Cohen and Bara-niuk. Cohen's method is a direct extension of his original formulation of TFRs, and Baraniuk's approach is based on a gro...

The paper reports on the experiments undertaken at the University of Wollongong to characterise delay parameters of an indoor wireless channel at 5GHz bandwidth. The measurements were undertaken at different locations around the campus with results recorded for a post-processing to calculate mean excess delay, r.m.s. delay spread, and the coherence bandwidth of the channel.
