Hi, Is echo path change a common problem in LEC. Is there any standard way of discriminating this with double talk. How adequate are methods which depend on the variance of the input signal for discrimination, particularly since tones send from one end can confuse such discriminators. Also, is this problem taken care of in standard echo cancellers available? Thanks, Sankar |
