Abstract
According to some embodiments, an input symbol may be received, and a hard symbol may be generated from the input symbol. A probability associated with the hard symbol may be calculated along with a probability associated with a previous hard symbol. An enhanced symbol may then be determined as a function of a comparison between the probability associated the hard symbol and the previous hard symbol.
Claims19
A method, comprising:
- receiving an input symbol at a probabilistic determinor;
- generating a hard symbol from the input symbol at a slicer;
- calculating a probability associated with the hard symbol;
- calculating a probability associated with a previous hard symbol;
- and
- determining an enhanced symbol as a function of a comparison between the probability associated the hard symbol and the previous hard symbol.
3 more elements
An apparatus, comprising:
- a distance calculator for calculating a distance between a hard symbol and a soft symbol;
- a parity bit probabilistic determinor for calculating a probability that a parity bit of the hard symbol is accurate as a function of at least an output of the distance calculator;
- a memory for storing a non-parity bit of a previous hard symbol;
- a comparator to compare the non-parity bit of the previous hard symbol to the parity bit of the hard symbol, wherein the comparator is to trigger an evaluator if the non-parity bit of the previous hard symbol is not equal to the parity bit of the hard symbol, and
- the evaluator is to evaluate if the probability that the parity bit of the hard symbol is accurate in greater than a probability that the parity bit of the previous hard symbol is accurate.
2 more elements
A system, comprising:
- a slicer;
- a probabilistic determinor coupled to the slicer, the probabilistic determinor to generate an enhanced symbol from a hard symbol of the slicer;
- a digitally programmed filter;
- a filter programmer coupled to the digitally programmed filter, the filter programmer to program the digitally programmed filter as a function of the enhanced symbol.
