A method and calibration of a system for iq - direct voltage offset - and asymmetry - calibration by the use of analytical formulae, desired compensation values to determine quickly

摘要

A method for determining a target inphase - - - direct voltage offset compensation value and a target - quadrature phase - - direct voltage offset compensation value which, in order to compensate for a dc voltage offset of a database (220) are used. The method comprises the steps of: inputting a reference signal in a database (220), which stores a plurality of compensation sets, each of which a inphase - - direct voltage offset compensation value and a quadrature phase - - direct voltage offset compensation value comprises, in order to provide a plurality of origin - offset - suppression values (oos - values) to be obtained, which correspond in each case to the compensation sets; and using the compensation sets and the oos - values, the target inphase - - - direct voltage offset compensation value and the target - quadrature phase - - direct voltage offset compensation value to calculate corresponding to an equation set.
