I don’t understand the middle part of in the folloing passage, please help me!
The article is about frequency-domain adaptive-filter acoustic echo canceller. An echo canceller includes an adaptive filter receiving the coefficients of a direct discrete transform in the frequency domain, said coefficients being calculated over a series of blocks in an input signal,
and driving, via an inverse transform circuit, the subtractive input of an adder for forming an output signal to the network,
and a filter coefficient adapting circuit. Said canceller is characterized in that the adapting circuit receives the coefficients of the series of transforms for the output signal sample blocks via a noise reducer. The adapting circuit receives the coefficients of the series of transforms for the output signal sample blocks via a noise reducer.
