Abstract:
A method of analysing signals in order to identify non-payload data elements in an incoming data stream, said incoming data stream comprising a payload data stream in which subsequent elements of the payload data stream are generated from antecedent elements of the payload data stream, said method comprising:(i) generating a comparison data stream with a predetermined relationship to the payload data stream for comparison with the payload data stream; (ii) detecting a mismatch between the incoming data stream and the comparison data stream; (iii) nominally identifying as a non-payload data element a data element which has a predetermined positional relationship, in the incoming data stream, to the data element with which the mismatch is detected; (iv) determining whether said nominally identified non-payload data element is a non-payload data element; and (v) repeating steps (ii) to (iv) until a nominally identified non-payload element is determined to be a non-payload data element.
