Abstract:
An equalizer for processing blocks of data comprising:a pre-processor, wherein the pre-processor applies coefficients b to a received signal, wherein the coefficients b comprise a window function having a duration substantially equal to a duration of a block of data plus a temporal separation between a main signal and a ghost of the main signal, and wherein pre-processor is arranged to provide a pre-processed output; a finite filter having an output, wherein the finite filter is arranged to substantially eliminate the ghost from the pre-processed output in order to provide a substantially ghost free signal at the output of the finite filter; and, a post-processor arranged to apply a window function to the output of the finite filter, wherein the window function has a duration substantially equal to a duration of a block of data, and wherein the post-processor applies coefficients c.
