Rigby, Alex R.; Olivier, J.C.; Myburgh, Hermanus Carel; Xiao, Chengshan; Salmon, Brian P. (SpringerOpen, 2018-08-02)The performance of a belief propagation decoder for low-density parity-check codes is limited by the presence of trapping sets in the code’s graph. This leads to an error floor at higher signal-to-noise ratios. We propose ...

De Sousa, K.C. (Karina); Smits, Cas; Moore, David R.; Myburgh, Hermanus C.; Swanepoel, De Wet (Lippincott Williams and Wilkins, 2022-05)OBJECTIVES : The digits-in-noise test (DIN) is a popular self-test measure that has traditionally been used to screen for hearing loss by providing either a pass or refer result. Standard approaches either tested each ear ...

Olatinwo, Damilola D.; Abu-Mahfouz, Adnan; Hancke, Gerhard P.; Myburgh, Hermanus Carel (Institute of Electrical and Electronics Engineers, 2023-06)Among the wireless body area network (WBAN) scarce resources, energy resource is an essential resource on which most of the WBAN biomedical devices activities depend upon. The biomedical devices are usually battery-powered ...

De Sousa, K.C. (Karina); Smits, Cas; Moore, David R.; Chada, Shelly; Myburgh, Hermanus Carel; Swanepoel, De Wet (Sage, 2022-09)OBJECTIVES : The objective of this study was to examine the uptake, user characteristics, and performance of the free WHO smartphone hearing screening test (hearWHO) as a global hearing health promotion initiative. METHOD ...

Lutakamale, Albert Selebea; Myburgh, Hermanus Carel; De Freitas, Allan (Elsevier, 2024-07)In recent years, low-power wide area networks (LPWANs), particularly Long-Range Wide Area Network (LoRaWAN) technology, are increasingly being adopted into large-scale Internet of Things (IoT) applications thanks to having ...

Oloyede, Muhtahir Oluwaseyi; Hancke, Gerhard P.; Myburgh, Hermanus Carel (Institute of Electrical and Electronics Engineers, 2018-11)The performance of most face recognition systems (FRSs) in unconstrained environments is widely noted to be sub-optimal. One reason for this poor performance may be the lack of highly effective image pre-processing ...
-
Otunniyi, Temidayo O.; Myburgh, Hermanus Carel (MDPI, 2021)With ever-increasing wireless network demands, low-complexity reconfigurable filter design is expected to continue to require research attention. Extracting and reconfiguring channels of choice from multi-standard receivers ...

Fourie, Christiaan Muller; Myburgh, Hermanus Carel (MDPI, 2022-04-15)Advanced driver-assistance system(s) (ADAS) are more prevalent in high-end vehicles than in low-end vehicles. Wired solutions of vision sensors in ADAS already exist, but are costly and do not cater for low-end vehicles. ...

Olatinwo, Damilola D.; Abu-Mahfouz, Adnan; Hancke, Gerhard P.; Myburgh, Hermanus C. (MDPI, 2023-03-08)Internet of things (IoT)-enabled wireless body area network (WBAN) is an emerging technology that combines medical devices, wireless devices, and non-medical devices for healthcare management applications. Speech emotion ...

Oosthuizen, Ilze; Picou, Erin M.; Pottas, Lidia; Myburgh, Hermanus Carel; Swanepoel, De Wet (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 ...
-
Myburgh, Hermanus Carel; Olivier, Jan Corne (Hindawi Publishing Corporation, 2013-02-08)In this article, it is proposed that a Hopfield neural network (HNN) can be used to jointly equalize and decode information transmitted over a highly dispersive Rayleigh fading multipath channel. It is shown that a HNN ...
-
Myburgh, Hermanus Carel; Olivier, Jan Corne (Hindawi Publishing Corporation, 2010)A soft output low complexity maximum likelihood sequence estimation (MLSE) equalizer is proposed to equalizeM-QAM signals in systems with extremely long memory. The computational complexity of the proposed equalizer is ...
-
Otunniyi, Temidayo O.; Myburgh, Hermanus Carel (MDPI, 2022-02-03)Realising a low-complexity Farrow channelisation algorithm for multi-standard receivers in software-defined radio is a challenging task. A Farrow filter operates best at low frequencies while its performance degrades ...
-
Ramakrishnan, Pasungili Rajesh; Myburgh, Hermanus Carel (CEUR Workshop Proceedings, 2019)A mean-offset classification technique was identified. It was found that the meanoffset classifier provides stability under dynamic indoor conditions and provides consistent results when training and test data combinations ...

Coetzer, Casper Johannes; Myburgh, Hermanus Carel; West, Nicolas; Walker, Jerry (Polish Academy of Sciences and Association of Polish Electrical Engineers, 2022-12)Solar-blind ultraviolet cameras as part of high-voltage electrical inspections until recently have mostly been used for pure observations. These observations only imply the presence of corona discharges and not the ...
-
Mokise, Kealeboga L.; Myburgh, Hermanus Carel (Springer Open, 2023-10-03)Powerline communication (PLC) channels are known to exhibit multipath propagation behaviour. The authors present a model-based framework to address the challenge of clustering multipath propagation components (MPCs) in ...
