    Abstract: A system may be for the correction of phase and amplitude errors. The system may receive a first input signal and a second input signal and supply a first output signal and a second output signal. The system may include two adders that supply the first and second output signals, respectively. The two adders may be configured for computing a sum of the first and second input signals, and multiplying the weighted sum by a third coefficient. Moreover, the first coefficient or the second coefficient of the first adder may be variable to enable correction of the phase errors, and the third coefficient of the second adder may be variable to enable correction of the amplitude errors.
