Soft-Output Signal Detection for Cetacean Vocalizations Using Spectral Entropy, K-Means Clustering and the Continuous Wavelet Transform
Marco W. Rademan, Daniel J. Versfeld, Johan A. du Preez
Underwater acoustic monitoring systems record many hours of audio data for marine research, making fast and reliable non-causal signal detection paramount. Such detectors assist in…
Optimization Algorithms for Improving the Performance of Permutation Trellis Codes
Oluwafemi Kolade, Mulundumina Shimaponda-Nawa, Daniel J. J. Versfeld +1
In this paper, soft-decision (SD) decoders of permutation trellis code (PTC) with -ary frequency shift keying are designed using three optimization algorithms and presented in f…
On the Resilience of Scalar and Vector Vortex Modes in Turbulence
Mitchell A. Cox, Carmelo Rosales-Guzmán, Martin P. J. Lavery +2
Free-space optical communication with spatial modes of light has become topical due to the possibility of dramatically increasing communication bandwidth via Mode Division Multiple…
