Abstract
A method for storing a constellation of Pulse Code Modulation (PCM) levels in a condensed representation. The constellation of PCM levels is stored in a condensed representation that can be expanded to the full constellation. A 16 bit binary word stores the full constellation of selected points. The 6 most significant bits represent a number of PCM linear values at the minimum spacing between PCM linear values that should not be selected in the constellation. The 10 least significant bits represent the minimum spacing between PCM linear values selected in the constellation from the condensed representation. Using the number of PCM linear values at the minimum spacing between PCM linear values that should not be selected in the constellation, the minimum spacing between PCM linear values, and the number of selected constellation points, the full constellation can be generated from the condensed representation.
