Abstract
A constellation mapping method, system, and apparatus are provided for mapping a received bit stream of data to a higher order symbol vector by processing a first set of selected bits from the received bit stream with a quadrant selector to identify a first quadrant offset vector corresponding a higher order quadrant in which an intended symbol is to be mapped, processing a second set of selected bits from the received bit stream with a 16-QAM mapper to identify a 16-QAM symbol vector, transforming the 16-QAM symbol vector into a transformed 16 QAM symbol vector based on the identified higher order quadrant, and combining the transformed 16-QAM symbol vector with the first quadrant offset vector to map the bit stream of data to a higher order symbol vector.
