Abstract
Official abstract text for this publication.
An apparatus and method is disclosed to compensate for one or more offsets in a communications signal. A communications receiver may carry out an offset adjustment algorithm to compensate for the one or more offsets. An initial search procedure determines one or more signal metric maps for one or more selected offset adjustment corrections from the one or more offset adjustment corrections. The offset adjustment algorithm determines one or more optimal points for one or more selected offset adjustment correction based upon the one or more signal maps. The adaptive offset algorithm adjusts each of the one or more selected offset adjustment corrections to their respective optimal points and/or each of one or more non-selected offset adjustment corrections to a corresponding one of a plurality of possible offset corrections to provide one or more adjusted offset adjustment corrections. A tracking mode procedure optimizes the one or more adjusted offset adjustment corrections.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus for compensating for an offset in a communication signal, comprising: an amplifier array configured to amplify the communication signal in accordance with a plurality of gain stages to provide an amplified communication signal, each of the plurality of gain stages being coupled to a corresponding summation network from among a plurality of summation networks; and an adaptive offset adjustment module configured to determine a signal metric base…
