A new blind calibration scheme for M time‐interleaved analogue‐to‐digital converters (ADCs), which models gain, time‐skew and bandwidth mismatches as components of a transfer function mismatch, is proposed. Numerical results on the emerging generation of WiFI IEEE 802.11.ac with 12‐bit ADCs show the effectiveness of the method.
