Adaptive noise-predictive partial-response equalization for channels with spectral nulls
P Chevillat, E Eleftheriou, D Maiwald - US Patent 5,784,415, 1998 - Google Patents
The present application makes use of a novel adaptive noise-predictive partial-response
equalization scheme for channels (30) exhibiting spectral nulls and/or near nulls. The noise-
predictive partial-response (PR) equalizer employed in the different embodiments of the
present invention consists of a linear PR equalizer (32) which shapes the channel response
to a predetermined partial-response function, followed by a linear predictor. This scheme
modifies the output sequence of said linear partial-response equalizer (32) by whitening the …
