可以用来测量线路回声消除效果的matlab程序-lines can be used to measure the effects of echo cancellation procedures Matlab

this document investigates on the quantization effect of implementing the adaptive algorithms for echo cancellers in fixedpoint DSP. Results show that the theoretical error is manifested at the ERLE of the canceller.-this document investigates on the

With a larger step size, the ERLE performance is not as good due to the misadjustment introduced by the near-end speech. To deal with this performance difficulty, acoustic echo cancellers include a detection scheme to tell when nearend speech is pres
