چکیده
In order to solve the problem of large error delay estimation in low SNR environment, a new method based on cross power spectral frequency domain weighting and spectrum subtraction is proposed. Through theoretical analysis MATLAB simulation, among four common functions, it proved that cross-power phase has good sharpening effect peak value cross-correlation function, verified improved generally noise reduction under different environments. Finally, joint simulation results whole algorithm show combination crosspower can effectively sharpen function improve accuracy time environment. The this paper provide useful help for sound source localization complex

Estimation of Wavefront Arrival Delay Using the Cross-Power Spectrum Phase Technique
In order to provide spatially selective sound capture in a teleconferencing environment, microphone array systems require accurate determination of the location of the desired source. Sound source location in turn relies on estimating time delay of arrival (TDOA) of a sound wave-front across a given microphone sensor pair. The cross-power spectrum phase (CPSP) method M. Omologo and P. Svaizer, ...
متن کاملA Method for Power Spectrum Parameter Estimation
An asymptotic analysis is carried out for an approximate method of estimating the parameters of the power spectrum of a zero-mean stationary Gaussian random process from an observed realization of limited duration. Maximum likelihood estimates are obtained with the approximation that the coefficients of the Fourier series expansion of the realization are uncorrelated. This is equivalent to othe...
متن کاملTime Delay Estimation for Speech Signal Based on FOC-Spectrum
Higher-order statistics can be used for time delay estimation (TDE) to suppress spatially correlated Gaussian noise, since the higher-order cumulant of Gaussian signal is always zero. However, third-order statistics is invalid for those signals with zero skewness, speech signal as a typical one. In this paper, the fourth-order cumulant (FOC) spectrum is derived, based on which a TDE algorithm t...
متن کاملPower Spectrum Estimation
Perhaps one of the more important application areas of digital signal processing (DSP) is the power spectral estimation of periodic and random signals. Speech recognition problems use spectrum analysis as a preliminary measurement to perform speech bandwidth reduction and further acoustic processing. Sonar systems use sophisticated spectrum analysis to locate submarines and surface vessels. Spe...
متن کاملFast Power Spectrum Estimation
We present a new algorithm to rapidly and optimally compute power spectra. This new algorithm is based on a generalization of iterative multigrid, and has computational cost O(N logN), compared to the standard brute force approach which costs O(N). The procedure retains this speed on the full sky and for ill-conditioned matrices. It is applicable to galaxy power spectra, CMB, polarization and w...
