| Abstract(in English) | A feedback structure and its learning algorithm are proposed for overcomplete blind source separation (BSS). The number of sources is larger than that of the sensors. In the proposed method, the signal sources are separated in several groups. Among them, at least one output can separate a single signal source under some condition. The outputs of the unmixing block are evaluated, which output provides a single signal source. The separated single signal source is fed back to the input node, and subtracted from the input signal, in order to reduce the number of equivalent signal sources. |
