The blind estimation technique is useful for an adaptive array antenna, a MIMO communication system and a cognitive wireless communication system. The independent component analysis (ICA) developing in the area of the image processing and the speech processing is a simple algorithm with demand upon less priori knowledge. In this report, it is described that an experiment of the blind signal separation...
Recently, there was a proposal of using the underdetermined blind source separation (BSS) principle to design image and speech encryption. In this paper, we report a cryptanalysis of this BSS-based encryption scheme and point out that it is not secure against known-/chosen-plaintext attack and chosen-ciphertext attack. In addition, we discuss some other security defects of the schemes: (1) it has...
In this paper we develop a new method for blind separation of temporally correlated sources, possibly dependent signals from linear mixtures of them. The proposed algorithm is based on the mutual independency of the innovations of source signals instead of original signals. This algorithm takes into account both the temporal structure and the high-order statistics of source signals and in contrast...
