Methods and systems for improving iterative signal processing

A method for iteratively decoding a set of encoded samples comprising:

• receiving the set of encoded samples;
• decoding the encoded samples using an iterative decoding process comprising:
• monitoring a level of a characteristic related to the iterative decoding process and providing a data signal in dependence thereupon;
• determining a scaling factor in dependence upon the data signal;
• and
• scaling the encoded samples using the scaling factor.

A scaling system comprising:

• an input port for receiving a set of encoded samples, the set of encoded samples for being decoded using an iterative decoding process;
• a monitor for monitoring at least one of a noise level of a transmission channel used for transmitting the encoded samples and a level of a characteristic related to the iterative decoding process and providing a data signal in dependence thereupon;
• scaling circuitry connected to the input port and the monitor, the scaling circuitry for determining a scaling factor in dependence upon the data signal and for determining scaled encoded samples by scaling the encoded samples using the scaling factor;
• and
• an output port connected to the scaling circuitry for providing the scaled encoded samples.

A method comprising:

• during an initialization phase receiving initialization symbols from a node of a logic circuitry;
• storing the initialization symbols in an edge memory;
• terminating the initialization phase when the received symbols occupy a predetermined portion of the edge memory;
• executing an iterative process using the logic circuitry storing output symbols received from the node in the edge memory;
• and,
• retrieving a symbol from the edge memory and providing the same as output symbol of the node.
