Hasan MK, Naylor PA, 2006, Analyzing effect of noise on LMS-type approaches to blind estimation of SIMO channels: Robustness issue, ISSN: 2219-5491
An analysis of the noise effect on the convergence characteristic of the least-mean-squares (LMS) type adaptive algorithms for blind channel identification is presented. It is shown that the adaptive blind algorithms misconverge in the presence of noise. A novel technique for ameliorating such misconvergence characteristic, using a frequency domain energy constraint in the adaptation rule, is proposed. Experimental results demonstrate that the robustness of the blind adaptive algorithms can be significantly improved using such constraints.
Mintandjian L, Naylor PA, 2006, A study of echo in VoIP systems and synchronous convergence of the μ-law PNLMS algorithm, ISSN: 2219-5491
A recent algorithm, the mu-law PNMLS, introduces a stepsize proportionate to the mu-law of the estimated tap coefficient to cancel sparse echo in telephony over packet-switch networks. It is derived by optimizing the following criterion: fastest convergence is obtained when all coefficients reach the vicinity of their target value at the same time. We present a study of synchronous convergence as introduced in this algorithm. Simulations for a 2-tap adaptive filter illustrate the optimality of mu-law PNLMS. We then compare the performances of this algorithm on multiple echo paths. This comparison shows some restrictions in the applicability of the optimality criterion and highlights possible improvements in robustness for this algorithm.
