Template-Based Estimation of Time-Varying Tempo
We present a novel approach to automatic estimation of tempo over time. This method aims at detecting tempo at the tactus level for percussive and nonpercussive audio. The front-end of our system is based on a proposed reassigned spectral energy flux for the detection of musical events. The dominant periodicities of this flux are estimated by a proposed combination of discrete Fourier transform...
متن کاملA Robust Adaptive Observer-Based Time Varying Fault Estimation
This paper presents a new observer design methodology for a time varying actuator fault estimation. A new linear matrix inequality (LMI) design algorithm is developed to tackle the limitations (e.g. equality constraint and robustness problems) of the well known so called fast adaptive fault estimation observer (FAFE). The FAFE is capable of estimating a wide range of time-varying actuator fault...

Observation probability • Probability to observe Yo(fk,tm) given tempo bi and RST mj 1) Compute the Yo(l,tm,bi) corresponding to the assumption bi 2) Select the mj which have a reference tempo Bj close to bi: (abs(log2(bi/Bj))<0.3785 3) Compute the one-minus cosine distance between Yo(l,tm,b) and mj=Yj(l) Template-Based Estimation of Tempo: Using Unsupervised or Supervised Learning to create be...
متن کاملPilot-based estimation of time-varying multipath channels
1 Reliable coherent communication over mobile wireless channels requires accurate estimation of time-varying multipath channel parameters. This paper addresses two issues in the context of direct-sequence code-division multiple access (CDMA) multipath channels: i) linear minimum-mean-squared-error (MMSE) channel estimation based on a pilot transmission, and ii) impact of channel estimation erro...
