Abstract
A digital audio processing system includes an input to receive a phase component of a signal. The digital audio processing system includes symbol recognition logic to adjust a sample of the phase component using an offset value. The symbol recognition logic maps the adjusted sample to a nearest predetermined phase value of a plurality of predetermined phase values. The symbol recognition logic determines a symbol using a difference between the nearest predetermined phase value and a prior nearest predetermined phase value. The prior nearest predetermined phase value corresponds to a prior sample of the phase component of the signal. The offset value is based on a detected error of the prior sample of the phase component of the signal. The digital audio processing system also includes an output to provide a second signal that indicates the symbol.
