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 15):
A receiver comprising:\n an analog-to-digital converter (ADC) configured to converted received analog signals to digital signals; an equalizer coupled to said ADC and configured to: generate equalized signals responsive to digital signals; and send said equalized signals as inputs to a slicer decision unit; said slicer decision unit coupled to said equalizer and 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 and configured to:\n access a first plurality of inputs; \n compare each of said first plurality of inputs with a first value; \n based on said comparing with said first value, determine a first count ratio of first inputs to said first plurality of inputs, wherein each of said first inputs is comprised in said first plurality of inputs and has a value encompassed in a first range that is defined by said first value; \n compare said first count ratio with a preset count ratio; \n determine an adapted constellation based on said first value and said comparing with said preset count ratio.
