METHOD FOR MODIFYING THE LMS ALGORITHM TO REDUCE THE EFFECT OF CORRELATED PERTURBATIONS

摘要

A process allows for the modification of the least-means-square (LMS) algorithm to remove perturbations associated with measured signals in an analog-to-digital converter (ADC). The process includes measuring the perturbations and determining a coefficient associated with the perturbations. The LMS algorithm is modified in accordance with whether a digital or an analog correction of the inter-stage error of a residue amplifier on the ADC is to be made.
