Method and system for processing digital data, corresponding apparatus and computer program product

A device, comprising:

• an input configured to receive digital data signals;
• digital signal processing circuitry configured to:
• produce from digital data signals a plurality of families of metrics, at least one family of the plurality of families allowing metric wrapping;
• compute a set of differences of metrics selected out of said plurality of families of metrics, the set of differences excluding differences between wrapping metrics of different families of the plurality of families of metrics;
• generate signals representative of order relationships of combinations of corresponding unwrapped metrics based on said set of differences;
• and
• decode the digital data signals based on the generated signals representative of order relationships.

A system, comprising:

• a plurality of selectors configured to:
• select metrics out of a plurality of families of metrics produced from digital data signals, at least one family of the plurality of families of metrics allowing metric wrapping;
• and
• compute a set of differences of metrics selected out of said plurality of families of metrics, the set of differences excluding differences between wrapping metrics of different families of the plurality of families of metrics;
• circuitry configured to generate signals representative of order relationships of combinations of corresponding unwrapped metrics based on said set of differences;
• and
• decoding circuitry configured to decode the digital data signals based on the generated signals representative of order relationships.
