Cyclic MPDR Beamforming for Suppression of Almost-Cyclostationary Acoustic Interference
Giovanni Bologni, Martin Bo Møller, Richard Heusdens +1
Conventional acoustic beamformers typically assume short-time stationarity and process frequency bins independently, ignoring inter-frequency correlations. This is suboptimal for a…
Harmonics to the Rescue: Why Voiced Speech is Not a Wss Process
Giovanni Bologni, Richard Heusdens, Richard C. Hendriks
Speech processing algorithms often rely on statistical knowledge of the underlying process. Despite many years of research, however, the debate on the most appropriate statistical…
Cyclic Multichannel Wiener Filter for Acoustic Beamforming
Giovanni Bologni, Richard Heusdens, Richard C. Hendriks
Acoustic beamforming models typically assume wide-sense stationarity of speech signals within short time frames. However, voiced speech is better modeled as a cyclostationary (CS)…
Optimal Privacy-Preserving Distributed Median Consensus
Wenrui Yu, Qiongxiu Li, Richard Heusdens +1
Distributed median consensus has emerged as a critical paradigm in multi-agent systems due to the inherent robustness of the median against outliers and anomalies in measurement. D…
