  • Abstract
    The stability of the noncanonical least mean square (NCLMS) algorithm is investigated. The NCLMS effectively uses a different step size for each tap coefficient position during adaptation. The classical LMS step size bound cannot be directly applied to the NCLMS. The weight error vector is modelled as a first order difference equation and a stability bound for the NCLMS is derived. Simulation results are presented to back up the analysis.
