Abstract

Methods and systems are provided for calibrating nonlinearity correction during analog-to-digital conversions on received analog signals. Correction-parameters may be estimated, such as to reduce, when applied to total spectral content, distortion resulting from the nonlinearity in originally-unoccupied spectral regions. Digital signals generated based on sampling of the received analog signals may then be corrected, to remove nonlinearity related distortion, based on the estimated correction-parameters. The nonlinearity correction calibration may be performed during reception and handling of the analog signals. The correction-parameters may be generated based on signals located in particular spectral regions, such as the originally-unoccupied spectral regions. These signals may be injected within the device, into the particular spectral regions, and the signal may have known characteristics to enable estimating the required correction.
