SIGNAL PATH PROCESSING BIAS ERROR DETECTOR

摘要

The present invention detects, determines, and mitigates signal-path processing errors. An extracted and inverted reference signal is compared to the carrier signal produced by various functional components to determine the error introduced to that signal by functional components. After the signal has been processed by various signal-processing components, the signal can once again be compared to the inverted reference signal so that a signal-path processing bias can be determined. Using that determination, a signal modification can be initiated to substantially reduce or eliminate all signal-path processing error.

主权项

1. A method for signal-path processing bias detection, the method comprising:
extracting from a first carrier signal a reference signal; inverting the reference signal submitting the first carrier signal to one or more functional components wherein the one or more functional components introduce to the first carrier signal a component error forming a second carrier signal; receiving at a signal detection and differencing component the second carrier signal and the inverted reference signal; averaging the inverted reference signal and the second carrier signal to identify the component error; processing the second carrier signal by one or more signal-path processing components wherein the one or more signal-path processing components introduce to the second carrier signal signal-path processing error forming a third carrier signal; receiving by a signal-path processing detector the inverted reference signal, the component error and the third carrier signal; and determining at the sign-path processing detector a signal-path processing error.
