A novel variable step-size sign natural gradient algorithm (VS-S-NGA) for online blind separation of independent sources is presented. A sign operator for the adaptation of the separation model is obtained from the derivation of a generalized dynamic separation model. A variable step size is also derived to better match the dynamics of the input signals and(More)
Blind signal processing (BSP) is attractive in the signal processing. Blind source separation (BSS) is one of the main components in blind signal processing. In this paper, the basic model and mathematical principle of BSS was presented. One of BSS algorithms, EASI (equivariant adaptive separation via independence), was reviewed. Then a new algorithm based(More)
