Patent ID: 7106782

Claim:
A method comprising: determining a phase rotation of a modulated signal that is caused by an adjustment of a characteristic of a circuit element associated with a signal path of the modulated signal, based on a gain control signal and a bias control signal; and performing a phase rotation compensation with respect to the modulated signal to compensate for the phase rotation caused by the adjustment of the characteristic of the circuit element, wherein the phase rotation compensation comprises rotating a phase of at least one of (a) a data signal, (b) a spreading sequence for spectrally spreading the data signal, and (c) a carrier signal for modulating the data signal, wherein performing the phase rotation compensation further comprises: determining a direction and an amount of the phase rotation of the modulated signal, wherein the direction and amount are associated with the gain control signal and the bias control signal; and rotating the phase of the modulated signal by an amount corresponding to the determined amount of the phase rotation in an opposite direction relative to the direction of the determined phase rotation.
