ABSTRACT:
A method is described for adjusting soft values in a code block prior to decoding. A count of saturated soft values in a code block is determined and one or more of the soft values in the code block are adjusted based on the count of saturated soft values. The count may be determined by incrementing the count for each positive saturated soft value and decrementing the count of each negative saturated soft value. The soft values may be adjusted by adding an offset computed based on the count to the soft values.
