Patent ID: 7697614

Claim:
A method for calibrating in an analog signal path associated with an Ultra Wideband (UWB) receiver, the analog signal path including a plurality of selectable analog gain stages and a compensation stage, the method comprising: receiving a plurality of symbols associated with an information signal in the analog signal path to form a plurality of received symbols, the plurality of received symbols whitened according to a whitening procedure, the information signal processed in the UWB receiver according to a plurality of gain configurations, the plurality of gain configurations including a plurality of combinations of ones of the plurality of analog gain stages; storing values of the plurality of received symbols obtained at a converter stage in a storage device in association with corresponding ones of the plurality of gain configurations that are active when respective ones of the plurality of received symbol are processed by the UWB receiver; and calculating an arithmetic mean when a predetermined number of the stored values associated with one of the plurality of gain configurations has been accumulated to form an offset value associated with the one of the plurality of gain configurations.
