| 摘要 |
The invention relates to a method for the simultaneous compensation of several signal errors that occur in an IQ-modulator (2), using respective inverse correction signals (Gain_I, Gain_Q, Offset_I, Offset_Q, Quadrature). According to the method, the optimised signal magnitude of each correction signal (Gain_I, Gain_Q, Offset_I, Offset_Q, Quadrature) is calculated by the determination of the effective signal error and by the subsequent iterative minimisation of the effective signal error. |
