Cascaded power symmetric IIR filter banks and continuity constrained adaptive algorithms for acoustic echo cancellation in subbands
Fig. 5. Comparison of the SRM-based algorithms for the " Bad " channel, SNR = 10 dB. SG: Standard stochastic gradient algorithm. Norm: Normalized stochastic gradient algorithm. SRM: Off-line SRM algorithm of [3], where S k is obtained at time k by averaging all of the data through time k to estimate ensemble averages. Conj Grad: Conjugate gradient algorithm. The results are averaged over 200 sa...
متن کاملGenetic algorithm for Echo cancelling
In this paper, echo cancellation is done using genetic algorithm (GA). The genetic algorithm is implemented by two kinds of crossovers; heuristic and microbial. A new procedure is proposed to estimate the coefficients of adaptive filters used in echo cancellation with combination of the GA with Least-Mean-Square (LMS) method. The results are compared for various values of LMS step size and diff...
متن کاملFast unbiased echo canceller update during ADSL transmission
This paper presents an efficient method for updating echo canceller (EC) coefficients in ADSL transceivers during transmission that removes the dependency of updates on the far end signal. The new method improves on the frequency domain EC architecture by Ho, Cioffi, and Bingham in that it converges faster, improves the stability to perturbation, and is not prone to bias from pilot tones. The n...
متن کاملFinal Iterations in Interior Point Methods | Preconditioned Conjugate Gradients and Modiied Search Directions
In this article we consider modiied search directions in the endgame of interior point methods for linear programming. In this stage, the normal equations determining the search directions become ill-conditioned. The modiied search directions are computed by solving perturbed systems in which the systems may be solved ef-ciently by the preconditioned conjugate gradient solver. We prove the conv...
متن کاملEcho cancellation for discrete multitone frame-asynchronous ADSL transceivers
In the past, several papers have reported on echo canceler (EC) structures developed for discrete multitone transmission (DMT) based asymmetric digital subscriber lines (ADSL) transmission. The most commonly known scheme, developed by Ho, Cioffi and Bingham, is based on canceling the received echo noise efficiently in time as well as in the frequency domain. The time domain processing part, whi...
