Abstract: Generally, in accordance with the various illustrative embodiments disclosed herein, an RF receiver can include an error correction system that executes a signal processing procedure upon a multi-tone digital I-signal and a multi-tone digital Q-signal to derive a wideband correction matrix. The wideband correction matrix can be used to correct one or more of: an amplitude error in any one or more frequency components of an RF input signal provided to the RF receiver, a phase error in any one or more frequency components of the RF input signal, a gain mismatch error between an analog I-signal circuit portion of the RF receiver and an analog Q-signal circuit portion of the RF receiver, or a phase mismatch error between the analog I-signal circuit portion of the RF receiver and the analog Q-signal circuit portion of the RF receiver.
