(Taylor and Francis, 2016-03)In this paper, we investigate joint design of quasi-cyclic low-density-parity-check (QC-LDPC) codes for coded cooperation system with joint iterative decoding in the destination. First, QC-LDPC codes based on the base ...
-
(Institution of Engineering and Technology, 2015-06)A target of interest measured by a high range resolution radar may be modelled by multiple dominant points of reflections referred to as dominant scatterers. In this paper a non-linear state space setting is used to model ...
-
(University of Pretoria, 2011-10-21)Technological innovation that empowers tiny low-cost transceivers to operate with a high degree of utilisation efficiency in multihop wireless mesh networks is contributed in this dissertation. Transmission scheduling and ...
-
(University of Pretoria, 2006-06-13)Using a Kalman filter that contains a forward-predictive model of a relevant system, to predict the states of that system by means of an analysis-by-synthesis implementation in order to evade significant time delays incurred ...
-
(Institute of Electrical and Electronics Engineers, 2014)A tapered ridge transition between coplanar waveguide and substrate-integrated waveguide is presented. The taper is implemented through staircase metallization across 10 layers of conventional RF substrate with sidewall ...
-
(Institute of Electrical and Electronics Engineers, 2012)Human settlement expansion is one of the most pervasive forms of land cover change in the Gauteng province of South Africa. A method for detecting new settlement developments in areas that are typically covered by natural ...
-
(Institute of Electrical and Electronics Engineers, 2012-06)It is proposed that the time series extracted from moderate resolution imaging spectroradiometer satellite data be modeled as a simple harmonic oscillator with additive colored noise. The colored noise is modeled with ...
-
(Elsevier, 2016-08)Building energy efficiency retrofit (BEER) projects are initiated in many nations and regions over the world. Existing studies of BEER focus on modeling and planning based on one building and one year period of retrofitting, ...
-
(University of Pretoria, 2021)Security is a key challenge for any IIoT network and more so for constrained IWSN deployments. Novel methods are thus required to enhance security, taking into consideration the lossy and low power nature of the IWSN. ...
-
(University of Pretoria, 2011)Although the majority of wireless receiver subsystems have moved to digital signal processing over the last decade, the low noise amplifier (LNA) remains a crucial analogue subsystem in any design being the dominant subsystem ...
-
(Elsevier, 2018-01)In this paper, the leader-following consensus problem is investigated for upper-triangular nonlinear MASs (multi-agent systems) via sampled and delayed output feedback. The sampled outputs transmitted through the communication ...
-
(University of Pretoria, 2018)Various solutions to the Simultaneous Localisation and Mapping (SLAM) problem have been proposed over the last 20 years. In particular, extending the fundamental solution of the SLAM problem has attracted a great deal ...
-
(University of Pretoria, 2021)Since the popularisation of media streaming, a number of video streaming services are continually buying new video content to mine the potential profit. As such, newly added content has to be handled appropriately to be ...
-
(Institute of Electrical and Electronics Engineers, 2013)It is desirable to limit the apparent target to one side of a retrodirective cross-eye jammer despite the variation caused by platform skin return. The relationship between the jammer parameters and the jammer-to-signal ...
-
(Institute of Electrical and Electronics Engineers, 2019)Traction power systems are susceptible to service affecting electrical faults or disturbances. These may cause interruptions of the power supply to the trains, affecting systems operations and causing major delays. ...
-
(Wiley, 2014-03)This article presents an adaptive predistortion (APD) linearization technique to improve the linearity of millimeter-wave power amplifiers (PAs), specifically at 60 GHz. The PA and the APD were designed using the 0.13 ...
-
(Emerald, 2017-05)PURPOSE : This work aims to improve upon the linearity of integrated CMOS current sensors used in switch mode power supply topologies, using a low-cost and low-voltage (less than 1.2 V) CMOS technology node. Improved sensor ...
-
(University of Pretoria, 2014)Wireless Sensor Networks have received significant attention due to their capability for distributed sensing at relatively low cost, in applications which range from environmental to industrial monitoring. More recently, ...
-
(American Speech-Language-Hearing Association, 2020-06)PURPOSE : It is not clear if behavioral indices of listening effort are sensitive to changes in signal-to-noise ratio (SNR) for young children (7-12 years old) from multilingual backgrounds. The purpose of this study was ...
-
(University of Pretoria, 2006-12-20)The increase in energy costs, restructuring of electricity supply industry, quality of supply standards and environmental responsibility, initiated an investigation to utilize available carbon monoxide for cogeneration at ...
