Closed-Form Estimators for Blind Separation of Sources - Part I: Real Mixtures
نویسندگان
چکیده
The problem of multiuser interference cancellation in wireless cellular communication systems accepts a blind source separation (BSS) model. The present contribution studies the closed-form solutions to BSS in the real-mixture case. Connections among a number of seemingly disparate methods are unveiled, new procedures are put forward, and their asymptotic (large-sample) performance is analyzed. Simulation experiments illustrate and validate the theoretical results. Altogether, a unifying generic framework for closed-form BSS methods is developed.

Closed-Form Estimators for Blind Separation of Sources - Part II: Complex Mixtures
The problem of multiuser detection in wireless communications systems adopts, in flat-fading channels, a blind source separation (BSS) formulation of instantaneous linear mixtures. This contribution addresses the closed-form solutions to BSS in the complex-mixture scenario. The algebraic devices which span a unifying framework for the complex BSS closed-form estimators are developed. With the a...
متن کاملA General Theory of Closed-form Estimators for Blind Source Separation
We present a general theory for the closed-form parametric estimation of the unitary mixing matrix after prewhitening in the blind separation of two source signals from two noiseless instantaneous linear mixtures. The proposed methodology is based on the algebraic formalism of bicomplex numbers and is able to treat both real and complex valued mixtures indiscriminately. Existing analytic method...
متن کاملClosed-form semi-blind separation of three sources from three real-valued instantaneous linear mixtures via quaternions
In the problem of blind source separation from instantaneous linear mixtures, a unitary transformation remains unknown after second-order spatial whitening. We present a novel approach for the identification of the orthogonal matrix in the real-valued three-signal scenario which, in contrast to existing procedures, operates in a single closed-form step, with no iterations. The new approach is b...
متن کاملBlind separation of independent sources for virtually any source probability density function
The blind source separation (BSS) problem consists of the recovery of a set of statistically independent source signals from a set of measurements that are mixtures of the sources when nothing is known about the sources and the mixture structure. In the BSS scenario, of two noiseless real-valued instantaneous linear mixtures of two sources, an approximate maximum-likelihood (ML) approach has be...
متن کاملBlind Separation of Sources from Their Delayed Mixtures
We give a near real-time algorithm for the blind separation of sources from mixtures of delayed sources. Many successful algorithms have been proposed for blind separation of instantaneous mixtures. For delayed mixtures only a few algorithms have been reported, and they assume only cross delays between mixed sources. Moreover, the weights and cross delays are updated in a batch mode, which is n...
