Adaptive Harmonic Spectral Decomposition for Multiple Pitch Estimation Emmanuel Vincent, Nancy Bertin and Roland Badeau
Multiple pitch estimation consists of inferring the fundamental frequencies and the salience of the notes forming a music signal over short time frames. This mid-level representation can be exploited as a front-end for higher-level applications, such as music-to-score transcription or chord detection. One approach is to decompose the short-term magnitude spectrum of the signal into a sum of bas...
متن کاملEmpirical Mode Decomposition based Adaptive Filtering for Orthogonal Frequency Division Multiplexing Channel Estimation
This paper presents an empirical mode decomposition (EMD) based adaptive filter (AF) for channel estimation in OFDM system. In this method, length of channel impulse response (CIR) is first approximated using Akaike information criterion (AIC). Then, CIR is estimated using adaptive filter with EMD decomposed IMF of the received OFDM symbol. The correlation and kurtosis measures are used to sel...
متن کاملA Spectral Decomposition Theorem for Certain Harmonic Algebras
Introduction. Let K be a simple ring with identity and let A be a harmonic ^-algebra with identity, where neither K nor A is assumed to be commutative. If one denotes the set of maximal ideals in A by Max(^4), then A is strongly semisimple iff S(A) = C\MGMBX(A) M = (0). We assume that A is strongly semisimple and note that this implies that A is Jacobson semisimple. One may equip Max(.4) with t...
متن کاملSpecmurt Analysis of Multi-Pitch Music Signals with Adaptive Estimation of Common Harmonic Structure
This paper describes a multi-pitch analysis method using specmurt analysis with iterative estimation of the quasioptimal common harmonic structure function. Specmurt analysis (Sagayama et al., 2004) is based upon the idea that superimposed harmonic structure pattern can be expressed as a convolution of two components, a fundamental frequency distribution and a ‘common harmonic structure’ functi...
متن کاملSpectral estimation via selective harmonic amplification
The state-covariance of a linear filter is characterized by a certain algebraic commutativity property with the state matrix of the filter, and also imposes a generalized interpolation constraint on the power spectrum of the input process. This algebraic property and the relationship between state-covariance and the power spectrum of the input allow the use of matrix pencils and analytic interp...
