| Abstract(in English) | A constrained learning algorithm is proposed to stabilize the Jutten's algorithm. The output samples with large amplitude are detected based on the standard deviation, and the learning is skipped for these output samples. Imbalance of the source signal powers is estimated by the correlation coefficient .of the observed signals. When the correlation coefficient is high, the correction term by the Jutten's algorithm becomes wrong value. Therefore, adjusting the parameters is skipped. Computer simulation using many kinds of signal sources have been carried out. The results demonstrate the proposed constrained learning algorithm works well for the signal sources with asymmetrical PDFs and imbalanced sigpal powers. |
