摘要：
An iterative method is proposed for the analysis of the steady-state weight fluctuations in an LMS-type adaptive FIR filter. without the widely used independence assumption, a power series of the weight-error correlation matrix is derived in terms of the stepsize Some new effects are observed, e.g., a decrease of the weight: fluctuations along the tapped-delay line.
