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…
LDPC codes: tracking non-stationary channel noise using sequential variational Bayesian estimates
J du Toit, J du Preez, R Wolhuter
We present a sequential Bayesian learning method for tracking non-stationary signal-to-noise ratios in LDPC codes using probabilistic graphical models. We represent the LDPC code a…
Efficient approximations of the multi-sensor labelled multi-Bernoulli filter
S. C. J. Robertson, C. E. van Daalen, J. A. du Preez
In this paper, we propose two efficient, approximate formulations of the multi-sensor labelled multi-Bernoulli (LMB) filter, which both allow the sensors' measurement updates to be…
