<p>According to the present invention a method for calibrating a six-port receiver as well as a receiving apparatus are provided. The receiving apparatus according to the present invention comprises a six-port receiver with a passive circuit (7) with two inputs, at least one input being supplied with a high frequency signal to be measured, and at least three outputs supplying power levels P1, P2, P3, P4 for a signal processing unit (10) which calculates a complex signal based on the at least three power levels P1, P2, P3, P4 and calibration coefficients. Furthermore the receiving apparatus according to the present invention comprises means (30, 35, 36) for supplying a predetermined calibration sequence with different symbols to the at least one input for the signal to be measured. The signal processing unit (10) calculates the calibration coefficients based on the calibration sequence.</p> |
