Resolving Measurement Errors Inherent with Time-of-Flight Range Imaging Cameras
… The major cause of measurement errors is multiple propagation paths from the light source to pixel, known as multi path interference. Multi-path interference typically arises from: inter reflections, lens flare, subsurface scattering, volumetric scattering, and translucent objects. This …

Design and testing of an acoustic ultra-short baseline navigation system
… ability to operate in an environment in which multipath interference is significant. A DSP microprocessor is used to process signals received by two hydrophones from a 26 kHz toneburst sound source. This processing power is used to implement features not commonly available with commercial …

MULTI-AGENT SOURCE LOCALIZATION USING PASSIVE SENSING
Purposeful collective behaviour in multi-agent systems can be achieved from a mix of simple individualistic and social behaviours of an agent. Social behaviours are the basis of cooperation in multi-agent systems and are fundamental in achieving collective behaviour. Practical implementation of …

Localization and Lensing of Fast Radio Bursts using CHIME/FRB and its VLBI Outriggers
… (CHIME) is perhaps the single most promising path towards uncovering the mystery of FRBs. CHIME detects about 700 FRBs per year, but lacks the resolution to pinpoint its bursts. Very-long baseline interferometry (VLBI) is a solution which uses widely-separated telescopes to achieve high …

Wireless Sensing and Fusion using Deep Neural Networks
… address this challenge, we first apply DNNs to multi-modal wireless signals, including Wi-Fi, an inertial measurement unit (IMU), and ultra-wideband (UWB). By formulating localization as a multi-modal sequence regression problem, a multi- stream recurrent fusion method is developed to combine …

A novel maximal-length sequence synchronisation network
… expense of bandwidth, make it attractive in a multitude of commercial applications. The most common method, and the one of interest in this thesis, of generating Spread Spectrum is multiplying the data waveform by a wideband, digitally generated waveform. This is referred to as Direct Sequence …
