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 1):
A method of dynamically determining adapted constellations for constellation selection in demodulation, the method comprising:\n accessing a first plurality of sampled inputs to a slicer and that are generated in response to a signal received at a receiver; comparing each of said first plurality of sampled inputs with a first value; based on said comparing with said first value, determining a first count ratio that represents a ratio of first sampled inputs to said first plurality of sampled inputs, wherein each of said first sampled inputs is comprised in said first plurality of sampled inputs and has a value encompassed in a first range that is defined by said first value; comparing said first count ratio with a preset count ratio; determining an adapted constellation based on said first value, and said comparing with said preset count ratio; and selecting said adapted constellation as an output in response to a sampled input based on one or more constellation selection thresholds.
