1. A data processing system, the data processing system comprising:
a known data based noise injection circuit operable to:
calculate a noise component based upon a data input and a corresponding known pattern;add a noise value derived from the noise component to a corresponding instance of the data input to yield a noise injected output; andselect one of the data input and the noise injected output as a processing input; a detector circuit operable to apply a data detection algorithm to the processing input to yield a detected output; and a bit error rate monitor circuit operable to generate a bit error rate based at least in part on a combination of the known pattern and the detected output.
