Fractional synchrosqueezing transform for enhanced multicomponent signal separation [PDF]
Scientific ReportsThe precise separation of multicomponent signals encounters numerous challenges due to the complexity of signals and widespread interference. Synchrosqueezing Transform (SST) is one of the important technologies for improving the accurate separation of ...

Flexible use of multimodal communicative strategies in adult chimpanzees [PDF]
Scientific ReportsHuman communication is remarkable for its flexibility, a trait largely reflected in its multimodal nature and shared to some extent with nonhuman primates.

Individual colour patches as multicomponent signals [PDF]
Biological Reviews, 2004 ABSTRACTColour patches are complex traits, the components of which may evolve independently through a variety of mechanisms. Although usually treated as simple, two‐dimensional characters and classified as either structural or pigmentary, in reality colour patches are complicated, three‐dimensional structures that often contain multiple pigment types ...

A Signal Complexity-Based Approach for AM–FM Signal Modes Counting
Mathematics, 2020 Frequency modulated signals appear in many applied disciplines, including geology, communication, biology and acoustics. They are naturally multicomponent, i.e., they consist of multiple waveforms, with specific time-dependent frequency (instantaneous ...

Analysis of Multicomponent Polynomial Phase Signals [PDF]
IEEE Transactions on Signal Processing, 2007 While the theory of estimation of monocomponent polynomial phase signals is well established, the theoretical and methodical treatment of multicomponent polynomial phase signals (mc-PPSs) is limited. In this paper, we investigate several aspects of parameter estimation for mc-PPSs and derive the Crameacuter-Rao bound.

The evolution of the multicoloured face of mandrills: insights from the perceptual space of colour vision. [PDF]
PLoS ONE, 2011 Multicomponent signals consist of several traits that are perceived as a whole. Although many animals rely on multicomponent signals to communicate, the selective pressures shaping these signals are still poorly understood.
