    A combined Kalman filter and natural gradient algorithm approach for blind separation of binary distributed sources in time-varying channels

    A combined Kalman filter and natural gradient algorithm approach for blind separation of binary distributed sources in time-varying channels by Maria G. Jafari, H.W. Seah, Jonathon Chambers

    Published 2001
    “…In situations where the mixing channel is nonstationary, the performance of the NGA is often poor. Typically, in such cases, an adaptive learning rate is used to help the NGA track the changes in the environment. …”

    Normalised natural gradient algorithm for the separation of cyclostationary sources

    Normalised natural gradient algorithm for the separation of cyclostationary sources by Maria G. Jafari, Jonathon Chambers

    Published 2003
    “…It improves the convergence properties of the cyclostationary natural gradient algorithm (CSNGA) by employing a gradient adaptive learning rate whose value changes in response to some change in the filter parameters. …”
