Abstract:
A method and device for the simultaneous compensation of several signal errors that occur in an IQ-modulator, using respective inverse correction signals, wherein the optimized signal magnitude of each correction signal is calculated by the determination of the effective signal error and by the subsequent iterative minimization of the effective signal error.
