Abstract
A method of decoding a digitally encoded signal having plural channels includes sampling a transient portion of a master filter mask, storing matched filter coefficients obtained from the sampling, receiving the digitally encoded signal, channelizing the digitally encoded signal into the plural channels, and generating a channel matched filter mask for each one of the plural channels using a subset of the stored coefficients. The method also includes filtering each one of the plural channels, in the frequency domain, based on the channel matched filter mask generated for each of the plural channels. Also disclosed are related methods using a burst reconstruction buffer, per channel distortion equalization, channel estimation and activity monitoring, and noise floor estimation, as well as corresponding apparatuses.
