Multi-dimensional error definition, error measurement, error analysis, error function generation, error information optimization, and error correction for communications systems
First Claim
1. A method for calibrating an electronic system, the method comprising:
- applying one or more input stimulus signals to the electronic system for a state of operation;
measuring an actual output of the electronic system for the state of operation;
generating a multi-dimensional error function, wherein the multi-dimensional error function comprises at least three dimensions and a plurality of calibration coefficients associated with a plurality of parameters that characterizes one or more actual input/output transfer characteristics of the electronic system; and
applying, with a processing unit, the plurality of calibration coefficients to the electronic system, wherein the plurality of calibration coefficients adjusts the actual input/output transfer characteristics based on the measured actual output of the electronic system to reduce a difference between the one or more actual input/output transfer characteristics of the electronic system and one or more desired input/output transfer characteristics of the electronic system.

Abstract
The present invention is related to multi-dimensional error definition, error measurement, error analysis, error function generation, error information optimization, and error correction for communication systems. Novel techniques are provided that can be applied to a myriad of applications for which an input to output transfer characteristic must be corrected or linearized. According to embodiments of the present invention, error can be described, processed, and geometrically interpreted. Compact formulations of error correction and calibration functions can be generated according to the present invention, which reduce memory requirements as well as computational time.
