This paper proposes to use separating matrix to control the step-size of on-line blind source separation algorithms for the first time. After detailed analyzing relevant fixed step-size and variable step-size equivariant adaptive source separation via independent algorithms, the paper presents a new adaptive step-size EASI algorithm.
