Acoustic Echo Cancellation Using Modified Variable Step Size Least Mean Square Adaptive Algorithm
this paper is focused on implementation of acoustic echo cancellation using modified variable step size least mean square algorithm (MVSSLMS) in LabVIEW. Simulation experiments are done to measure its performance and compared with other conventional variable step size algorithms. Results show better performance of MVSSLMS over other algorithms in terms of echo return loss enhancement (ERLE), es...
متن کاملSingle and Multiple -Variable Step Size Normalized Least Mean Square Algorithms for Network Echo Cancellation
In this paper, we propose improved versions of normalized least mean square (NLMS) algorithm: single and multiple -variable step size normalized least mean square (VSSNLMS) algorithms for echo cancellation. The presented algorithms exhibit faster convergence rate in comparison to NLMS algorithm. Simulation results employing standard figure of merits show how the algorithms perform better than N...
متن کاملAdaptive Noise Cancellation using Modified Normalized Least Mean Square Algorithm
This paper presents an efficient design of Adaptive filters which uses enhanced NLMS algorithm for eliminating noise added by mean of various communication media or any other noise sources. By using the appropriate weights, Adaptive filter estimates and remove the estimated noise signal from the available information. LMS and Normalized LMS are two most efficient algorithm for noise cancelation...
متن کاملWiener variable step size and gradient spectral variance smoothing for double-talk-robust acoustic echo cancellation and acoustic feedback cancellation
Double-talk (DT)-robust acoustic echo cancellation (AEC) and acoustic feedback cancellation (AFC) are needed in speech communication systems, e.g., in hands-free communication systems and hearing aids. In this paper, we derive a practical and computationally efficient algorithm based on the frequency-domain adaptive filter prediction error method using row operations (FDAF-PEM-AFROW) for DT-rob...
متن کاملA Variable Step-size Proportionate Nlms Algorithm for Echo Cancellation
The proportionate normalized least-mean-square (PNLMS) algorithms were developed in the context of network echo cancellation. They outperform the normalized leastmean-square (NLMS) algorithm only when the echo path is sparse. Unfortunately, realworld network echo path may not be that sparse sometimes, while the acoustic echo paths are usually less sparse. The improved PNLMS (IPNLMS) algorithm i...
