Benders decomposition of the passive optical network design problem
Van Loggerenberg, S.P.; Ferreira, M.; Grobler, M.J.; Terblanche, S.E. (Elsevier, 2016)Similar to the connected facility location problem, the passive optical network design problem requires the search for a subset of deployed distribution points (splitters) as well as an allocation of demand points (optical ... -
A comparison of clustering algorithms for automatic modulation classification
Mouton, Jacques P.; Ferreira, Melvin; Helberg, Albertus S.J. (Elsevier, 2020)In this paper, the k-means, k-medoids, fuzzy c-means, Density-Based Spatial Clustering of Applications with Noise (DBSCAN), Ordering Points To Identify the Clustering Structure (OPTICS), and hierarchical clustering algorithms ... -
Comparison of Dynamic Spectrum Access schemes in a common system model
Rananga, S. (North-West University, 2019)The fourth generation (4G) and fifth generation (5G) mobile networks performance have been predicted through a broad consensus that they will not come close to meeting the demands that networks will face in the next decade. ... -
Optimal passive optical network planning under demand uncertainty
Van Loggerenberg, S.P.; Ferreira, M.; Grobler, M.J.; Terblanche, S.E. (SATNAC, 2014)As a result of ever-increasing demand for access level bandwidth, long deployment cycles and the popularisation of more economically viable Point-to-Multipoint (P2MP) networks, service providers are moving to extensively ... -
Received power prediction of a terrestrial TV broadcasting transmitter using ordinary kriging interpolation
Boshoff, Willem H.; Grobler, Magdalena J.; Ferreira, Melvin (SATNAC, 2014)Radio Environment Mapping (REM) provides information useful for many different applications in the telecommunications field. In this paper, the authors evaluate the ability of ordinary kriging (OK) to produce a REM ... -
White space and digital dividends: the case for dynamic spectrum access in South Africa
Ferreira, Melvin; Helberg, Albert (IEEE, 2011)In this paper we present the current state of affairs surrounding the analog switch-off and corresponding digital dividend as pertaining to South Africa. Analog switch-off and digital dividends has enjoyed much attention ...
