Abstract
A symbol de-mapper can determine soft values for the bits of a complex symbol R that has been transmitted and received at a receiving device. The symbol de-mapper can reduce the number of calculations needed to determine soft values of the bits by limiting the symbols S utilized to calculate the soft values to subsets of the symbols S associated with sectors of symbol rings in the symbol constellation.
