Joint time delay and frequency estimation of multiple sinusoids
نویسندگان
چکیده
In this paper, we devise a new subspace method for estimating the di erential time delay of a signal received at two separated sensors as well as the frequencies of the source signal, assuming that it consists of multiple sinusoids. The time delay and frequency estimates are related to the eigenvalues and eigenvectors of a matrix obtained from the covariances of the received signals. The e ectiveness of the proposed algorithm is demonstrated via computer simulations using sinusoidal signals as well as real speech data.

متن کاملPolyphonic Pitch Tracking Using Joint Bayesian Estimation of Multiple Frame Parameters
We present a novel approach to pitch estimation and note detection in polyphonic audio signals. We pose the problem in a Bayesian probabilistic framework, which allows us to incorporate prior knowledge about the nature of musical data into the model. We exploit the high correlation between model parameters in adjacent frames of data by explicitly modelling the frequency variation over time usin...
متن کاملNewtonized Orthogonal Matching Pursuit for Line Spectrum Estimation with Multiple Measurement Vectors
A Newtonized orthogonal matching pursuit (NOMP) algorithm is proposed to estimate continuous frequencies and amplitudes of a mixture of sinusoids with multiple measurement vectors (MMVs). The proposed algorithm includes two key steps: Detecting a new sinusoid on an oversampled discrete Fourier transform (DFT) grid and refining the parameters of already detected sinusoids to avoid the problem of...
متن کاملFrequency Estimation of Multiple Sinusoids with Three Sub-Nyquist Channels
Frequency estimation of multiple sinusoids is significant in both theory and application. In some application scenarios, only sub-Nyquist samples are available to estimate the frequencies. A conventional approach is to sample the signals at several lower rates. In this paper, we address frequency estimation of the signals in the time domain through undersampled data. We analyze the impact of un...
متن کاملFrequency Estimation of Multiple Sinusoids with Sub-Nyquist Sampling Sequences
In some applications of frequency estimation, the frequencies of multiple sinusoids are required to be estimated from sub-Nyquist sampling sequences. In this paper, we propose a novel method based on subspace techniques to estimate the frequencies by using under-sampled samples. We analyze the impact of under-sampling and demonstrate that three subNyquist sequences are general enough to estimat...
