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.

PCFCRD for multicomponent LFM signals analysis
Electronics Letters, 2017 A novel extension of the cubic phase function (CPF), known as the parameterised centroid frequency‐chirp rate distribution (PCFCRD), is proposed for multicomponent linear frequency modulated signals analysis. The PCFCRD is coherent and introduces a constant delay to reduce the noise correlation. Mathematic analysis and numerical simulations demonstrate

A pde-Based Analysis of the Spectrogram Image for Instantaneous Frequency Estimation
Mathematics, 2021 Instantaneous frequency (IF) is a fundamental feature in multicomponent signals analysis and its estimation is required in many practical applications. This goal can be successfully reached for well separated components, while it still is an open problem

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 ...

Towards Intelligent Data Analytics: A Case Study in Driver Cognitive Load Classification
Brain Sciences, 2020 One debatable issue in traffic safety research is that the cognitive load by secondary tasks reduces primary task performance, i.e., driving. In this paper, the study adopted a version of the n-back task as a cognitively loading secondary task on the ...

Multivariate Decomposition of Acoustic Signals in Dispersive Channels
Mathematics, 2021 We present a signal decomposition procedure, which separates modes into individual components while preserving their integrity, in effort to tackle the challenges related to the characterization of modes in an acoustic dispersive environment.

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.

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 ...
