advanced blind-signal separation technology is not). But, in fact, in addition to this mixed signal, we can get the original signal that produces the echo, although it is different from the echo signal. We look at the following AEC Acoustic echo cancellation block Diagram (reproduced in this image).
Among them, we can get two signals: one is the blue and red mixed signal 1, that is, the actual need to send the speech and the actual unwanted echo mixed voice flow, and the other is the dashed sig

specification, each file is preceded by a character that represents the encoding sequence, which is named "0-width non-newline space" (ZERO wide no-break space), denoted by Feff. This happens to be two bytes, and FF is 1 larger than FE.If the first two bytes of a text file are Fe FF, it means that the file is in a large head, and if the first two bytes are FF FE, it means that the file is in a small way.8.
