An adaptive all-digital blind compensation of Dual-TIADC frequency-response mismatch based on complex signal correlations

The paper introduces an adaptive all-digital architecture for dual-TIADC frequency-response mismatch compensation based on a linear periodic time-varying correction.

Parameters of the correction are estimated using correlations of the complex signal derived from the TIADC output. Simulation results of the compensation technique based on real and generated data demonstrate the efficiency of our method.
