Pulse position modulation-ultra wideband (PPM–UWB) communication signal is hard to detect and sample directly, owing to its ultra-low power spectral density and wide bandwidth. There are already some researches on using analogue-to-information converter (AIC) technology and compressed sensing (CS) theory to under-sample and detect PPM-UWB communication signal, utilising its sparseness in time domain...
This paper presents a new method of zero-crossing based binaural mask estimation for missing data speech recognition under the condition that multiple sound sources are present simultaneously. The masking is determined by the estimated directions of sound sources using the spatial cues such as inter-aural time differences (ITDs) and inter-aural intensity differences (IIDs). In the suggested method,...
