Fig. 9From: An overview on optimized NLMS algorithms for acoustic echo cancellationPerformance of the algorithms for AR(1) input. Misalignment of the NLMS (for different values of α), NPVSS-NLMS, JO-NLMS, and OSS-NLMS-id algorithms. The input signal is an AR(1) process; echo path changes at time 20 s, L=512, and SNR = 20 dBBack to article page
