Decorrelation: Measurement, Process & Overview

Decorrelation is a general term for any process that is used to reduce autocorrelation within a signal, or cross-correlation within a set of signals, while preserving other aspects of the signal.[citation needed] A frequently used method of decorrelation is the use of a matched linear filter to reduce the autocorrelation of a signal as far as possible.…
