Abstract:
System and method of demodulation by adapting constellation values based on statistic distributions of received data symbols. To determine an adapted constellation, an expected ratio of received symbols with values in a certain range is preset based on an expected statistic distribution of data symbols across the multiple constellations. For a set of received symbols, a count ratio of symbols falling in a first range to all the symbols in the set is compared with the expected ratio, where the first range is defined as below a first value. The first value is repeatedly adjusted to adjust the first range until the count ratio equals the expected ratio. The final fist value is then designated as the optimal adapted constellation.

Claim (Index 9):
A device comprising:\n a slicer decision unit configured to:\n select a first constellation as an output responsive to an input greater than a threshold; and \n select a second constellation as an output responsive to an input smaller than said threshold; and \n a constellation adaptation unit coupled to said slicer decision unit comprising:\n a comparator configured to compare each of a first plurality of inputs with a first value, wherein said first plurality of inputs are supplied to said slicer decision unit; \n a first counter configured to, responsive to comparison decisions output from said comparator, produce a number of first inputs comprised in said first plurality of inputs and each having a value encompassed in a first range, wherein said first range is defined by said first value; and \n logic configured to:\n determine a first count ratio of said number of said first inputs to a total number of said first plurality of inputs; \n determine an adapted constellation based on said first value and said first count ratio; and \n send said adapted constellation to said slicer decision unit.
