View Patent ↗Signal processing and/or signal modulation includes tracking a phase parameter; determining a discontinuity; and compensating for the discontinuity.
1. A method for data processing, comprising:
tracking, by a processor in a data processing system, a phase parameter;
determining a discontinuity in operation of the data processing system based on a drop and/or a jump condition, and a trend condition indicating whether a phase value has been increasing or decreasing within a predetermined number of samples to produce a difference substantially larger than 2π between a current phase value and a preceding phase value; and
compensating for the discontinuity.
2. The method according to claim 1 , wherein the method utilizes an adaptive delta modulator.
3. The method according to claim 2 , wherein the discontinuity is based on an a cyclic overflow event.
4. The method according to claim 3 , wherein the phase parameter includes at least one Givens parameter.
5. The method according to claim 4 , wherein said compensating for the discontinuity includes subtracting or adding 2π from a recently quantized value.
6. The method according to claim 5 , wherein a flag signal indicates the discontinuity in a cyclic overflow mode.
7. The method according to claim 6 , an encoder performs said tracking, determining and compensating.
8. The method according to claim 7 , wherein the data processing includes signal processing and/or modulating a signal.
9. A method for data processing comprising:
compensating for a discontinuity of a drop and/or a jump condition of a phase parameter received, based on a flag signal, and a trend condition indicating whether a phase value has been increasing or decreasing within a predetermined number of samples to produce a difference substantially larger than 2π between a current phase value and a preceding phase value.
10. The method according to claim 9 , wherein the flag signal indicates a cyclic overflow mode.
11. The method according to claim 10 , wherein said compensating for the discontinuity includes subtracting or adding 2π from a recently quantized value.
