Abstract
A system includes a receiver for receiving a modulated signal. The receiver includes a gain estimator for converting complex data representative of constellation points of the modulated signal into scalar data representation. The gain estimator is configured to fold a first portion of the scalar data representation onto a second portion of the scalar data representation. The gain estimator is further configured to estimate a constellation gain value from the folded first portion and the second portion of the scalar data representation.
