  • Abstract
    It is proposed that the convergence factor μ in the adaptive filter can be made time-varying according to the gradient of the performance surface. Computer simulations show that when a suitable damping parameter, α, is used, the algorithm possesses a fast convergence rate and yields very small misadjustment. The algorithm works well under nonstationary environments, in sharp contrast with the two-stage method
