ab: Summary: Available convergence analyses of adaptive active noise control
    systems apply to only theoretical cases with broad-band white noise or
    pure delay secondary paths. In order to investigate convergence
    behaviors of these systems in more practical conditions, this paper
    conducts a new convergence analysis for filtered-x LMS-based active
    noise control systems with band-limited white noise and moving average
    secondary paths. A linear model for the adaptation process is
    developed. Based on this model, the upper-bound of the adaptation
    step-size is derived. Also, the adaptation step-size leading to the
    fastest convergence rate is derived. In addition to the computer
    simulation, a fully implemented real time active noise control system
    is used to verify the validity of the analytical results.
