Correlated modulation: a criterion for blind source separation
نویسنده
چکیده
The problem of blindly separating a convolutive mixture of modulated signals is considered. Spectrograms of the signals are computed and separation is performed in the frequency domain. A new algorithm for blind source separation is proposed, which is based on correlated modulation in the sources’ different frequency channels. For example, speech contains correlated modulation in different frequency regions. The algorithm successfully separates mixtures of modulated artificial signals and of speech. To appear in: Joint meeting of the Acoustical Society of America and the European Acoustics Association, Berlin, Germany, March 14-19, 1999.

Blind Separation of Jointly Stationary Correlated Sources
The separation of unobserved sources from mixed observed data is a fundamental signal processing problem. Most of the proposed techniques for solving this problem rely on independence or at least uncorrelation assumption for source signals. This paper introduces a technique for cases that source signals are correlated with each other. The method uses Wold decomposition principle for extracting ...
متن کاملBlind Signal Separation Using an Extended Infomax Algorithm
The Infomax algorithm is a popular method in blind source separation problem. In this article an extension of the Infomax algorithm is proposed that is able to separate mixed signals with any sub- or super-Gaussian distributions. This ability is the results of using two different nonlinear functions and new coefficients in the learning rule. In this paper we show how we can use the distribution...

متن کاملWavelet De-noising for Blind Source Separation in Noisy Mixtures
Blind source separation, which supposes that the sources are independent, is a well known domain in signal processing. However, in a noisy environment the estimation of the criterion is harder due to the noise. In strong noisy mixtures, we propose two new principles based on the combination of wavelet de-noising processing and blind source separation. We compare them in the cases of white/corre...
متن کاملA unifying criterion for instantaneous blind source separation based on correntropy
Correntropy has recently been introduced as a generalized correlation function between two stochastic processes, which contains both high-order statistics and temporal structure of the stochastic processes in one functional form. Based on this blend of high-order statistics and temporal structure in a single functional form, we propose a unified criterion for instantaneous blind source separati...
