摘要：
In a method of decoding a data signal (WSS) having at least a start-code or sync word section (SC) and a data section (AR..R), the data signal is converted (ADC) into a sequence of multi-bit samples having at least a start-code or sync word section (SC) and a data section (AR..R). The sequence of multi-bit samples is processed (11A) to obtain a word sync signal (WS) indicating synchronization information. A disturbance measurement signal (.GAMMA.) is obtained (19) from at least the start-code or sync word section (SC) of the sequence of multi-bit samples. Finally, the data section (AR..R) of the sequence of multi-bit samples is code demodulated (13A) in response to the word sync signal (WS) in dependence upon the disturbance measurement signal (.GAMMA.) to obtain a demodulated data signal.
