(University of Pretoria, 2010)Acoustic models are useful tools to increase understanding of cochlear implant perception. Two particular issues in modelling cochlear implant perception were considered in the present study, which aimed at improving ...
-
(University of Pretoria, 2011)Cochlear implant (CI) devices afford many profoundly deaf individuals worldwide partially restored hearing ability. Although CI users achieve remarkable speech perception with contemporary multichannel CI devices, their ...

(University of Pretoria, 2009-12-08)This report presents an investigation into some merging options between an upper-layer Bluetooth (BT) protocol stack with a lower-layer ECMA-368/9 Ultra Wideband (UWB) radio connection. A Bluetooth over Ultra Wideband ...
-
(University of Pretoria, 2009-12-09)In mobile communications, using multiple transmit and receive antennas has shown considerable improvement over single antenna systems. The performance increase can be characterized by more reliable throughput obtained ...
-
(University of Pretoria, 2013-01-09)On-chip impedance tuning is used to overcome IC perturbations caused by packaging stress. Tuning is more important for matching networks of radio frequency (RF) systems. Possible package resonance and fabrication process ...
-
(University of Pretoria, 2008)Closed-loop system identification and fault detection and isolation are the two fundamental building blocks of process monitoring. Efficient and accurate process monitoring increases plant availability and utilisation. ...
