06498929 is referenced by 71 patents.

A receiver having a function of a direct current offset, and including a receiving section for receiving a radio frequency signal, an analog signal processing section for amplifying, band-converting and frequency-converting an analog signal inputted from the receiving section, and an AD converting section for converting an output of the analog signal processing section from an analog signal to a digital signal. Also included is a digital signal processing section for processing the digital signal converted by the DC converting section. The receiver further includes an offset detecting element, provided in the digital signal processing section, for detecting a direct current offset signal produced in the receiving section or a frequency converting section, an offset holding element, provided in the digital signal processing section, for holding the direct current offset signal detected by the offset detecting element, a DA converting section for converting the direct current offset signal detected by the digital signal processing section into an analog signal, and a first offset correcting element, provided in the analog signal processing section, for correcting the analog signal on the basis of the direct current offset signal converted by the DA converting section into the analog signal.
