| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The convergence properties of stereo echo cancelers (SECs) with pre-processing were examined. SECs have a slow convergence speed due to the non-uniquness of the equilibrium but they are accelerated by applying the input-sliding method, which introduces a time-varying pre-processing to the input of one channel. When SECs have the pre-processing in both channels, they have a faster convergence rate. However, its reason is still unknown. We extended the method for analyzing the input-sliding method to the one with both channels and derived the convergence rate, which is faster than the conventional one. | |
