Combined estimation scheme for blind source separation with arbitrary source PDFs
An alternative closed-form estimator for blind source separation based on fourth-order statistics is presented. In contrast to other estimators, the new estimator works well when the source kurtosis sum is zero. Arbitrary source PDFs are successfully treated through a combined estimation scheme base...

Zusammenfassung: | An alternative closed-form estimator for blind source separation based on fourth-order statistics is presented. In contrast to other estimators, the new estimator works well when the source kurtosis sum is zero. Arbitrary source PDFs are successfully treated through a combined estimation scheme based on a heuristic decision rule for choosing between the new estimator and an existing estimator. |
