摘要

A method for reducing a set (20) of digital data samples (A0, A1, A2, A3, A4, A5, A6, A7, A8, A9) with a first size in a second set (40) of digital data samples (C0, C1, C2, C3, C4) with unsegundo smaller than the first size, comprising the steps of size: - match each sample of a first subset of samples (A1, A3, A5, A7, A9) the first set (20) of digital data with a neighboring sample of a second subset of samples (A0, A2, A4, A6, A8) of primerconjunto (20) of digital data, wherein the first subset of samples are interleaved ( A1, A3, A5, A7, A9) and elsegundo subset of samples (A0, A2, A4, A6, A8); - approximating an error for each equated sample, the error is a difference between the sample primersubconjunto of samples (A1, A3, A5, A7, A9) and the corresponding matched sample; - extracting samples from the equalized digital data set of samples (A0, A1, A2, A3, A4, A5, A6, A7, A8, A9) resulting in the second set (40) of digital data; and - integrate approximate errors in the least significant bits of the samples.
