Abstract:
System and method of adapting thresholds for constellation selection based on statistic distributions of received data symbols. To determine an adapted threshold, 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. A first and a second ratios are defined based on the expected ratio, the first ratio being the expected ratio minus an error ratio and the second ratio being the expected ratio plus the error ratio. A first value is determined which makes the received symbols in a firs range to constitute the first ratio of a set of slicer inputs. A second value is determined which makes the received symbols in the second range to constitute the second ratio of a set of slicer outputs. The adapted threshold is then obtained based on the first and the second value.

Claim (Index 9):
A device comprising:\n a slicer decision unit configured to:\n produce a first output value responsive to an input greater than a threshold; and \n produce a second output value responsive to an input smaller than said threshold; and \n a threshold 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; and \n determine a first threshold of said slicer decision unit based on said first value and said first count ratio.
