Perceptually-Motivated Nonlinear Channel Decorrelation For Stereo Acoustic Echo Cancellation
Jean-Marc Valin
Acoustic echo cancellation with stereo signals is generally an under-determined problem because of the high coherence between the left and right channels. In this paper, we present…
A New Robust Frequency Domain Echo Canceller With Closed-Loop Learning Rate Adaptation
Jean-Marc Valin, Iain B. Collings
One of the main difficulties in echo cancellation is the fact that the learning rate needs to vary according to conditions such as double-talk and echo path change. Several methods…
On Adjusting the Learning Rate in Frequency Domain Echo Cancellation With Double-Talk
Jean-Marc Valin
One of the main difficulties in echo cancellation is the fact that the learning rate needs to vary according to conditions such as double-talk and echo path change. In this paper w…
An Iterative Linearised Solution to the Sinusoidal Parameter Estimation Problem
Jean-Marc Valin, Daniel V. Smith, Christopher Montgomery +1
Signal processing applications use sinusoidal modelling for speech synthesis, speech coding, and audio coding. Estimation of the model parameters involves non-linear optimisation m…
