摘要： The disclosure relates to a receiver system that employs multiple instances of a DC compensation system to reduce DC offsets in a receiver path. The receiver has a receiver front end configured to receive an RF input signal and to operate on the RF input signal according to a plurality of receiver states to generate a baseband signal having a DC offset that is based upon the plurality of receiver states. A DC offset compensation circuit implements a plurality of instances of DC offset compensation components that respectively generate an estimated DC offset corresponding to a receiver state. A controller controls the receiver state of the receiver front end and operates the DC offset elimination circuit to selectively apply one of the plurality of DC compensation components to the corresponding baseband signal based upon the receiver state.

摘要： A signal processing device is provided that includes a modulation unit that produces an amplitude element as well as a phase element from components that are applied thereto. A correction device is also provided, in which at least one of the components is supplied and is compared with an ideal nominal value. This is used to produce a correction factor, which is multiplied by the component which has been compared with the nominal value. The correction factor determined is used to correct any offset or distortion of the components produced by analog circuits.
