Method and an apparatus for a waveform quality measurement
First Claim
1. A waveform quality measurement apparatus, comprising:
- an optimization circuit configured to provide a plurality of offsets of parameters of an actual signal with respect to an ideal signal;
a compensation circuit configured to compensate the actual signal with the plurality of offsets to generate a compensated actual signal;
a filtering circuit configured to filter the compensated actual signal to generate a filtered signal; and
a processor configured to modify the ideal signal to correspond to the filtered signal to generate a modified signal, and configured to determine the waveform quality measurement in accordance with the modified ideal signal and the filtered signal.

Abstract
A method and an apparatus for waveform quality measurement are disclosed. An actual signal, representing a waveform channelized both in time and in code is generated by, e.g., an exemplary HDR communication system. Test equipment generates an ideal waveform corresponding to the actual waveform. The test equipment then generates an estimate of offsets between parameters of the actual waveform and the ideal waveform, and the offsets are used to compensate the actual waveform. The test equipment then evaluates various waveform quality measurements utilizing the compensated actual waveform and the corresponding ideal waveform. Definitions of the various waveform quality measurements as well as conceptual and practical examples of processing of the actual waveform and the corresponding ideal waveform by the test equipment are disclosed. The disclosed method and apparatus may be extended to any waveform channelized both in time and in code regardless of the equipment that generated the waveform.
