摘要
A method for determining a target in-phase DC offset compensation value and a target quadrature-phase DC offset compensation value used for compensating DC offset of a database. The method includes: inputting a reference signal into a database which stores a plurality of compensation sets, each having an in-phase DC offset compensation value and a quadrature-phase DC offset compensation value to obtain a plurality of origin offset suppression (OOS) values corresponding to the compensation sets, respectively; and utilizing the compensation sets and the OOS values to compute the target in-phase DC offset compensation value and the target quadrature-phase DC offset compensation value according to an equation set.
