Patent ID: 7313198

Claim:
A transmit path correction system comprising: a mixed signal forward path operable to process input data symbols to produce at least one baseband analog output signal, wherein the mixed signal forward path includes: a digital DC offset correction circuit operable to compensate for DC offsets in the mixed signal forward path using at least one digital feedback signal, and at least one digital to analog converter operably coupled to an output of the digital DC offset correction circuit and operable to at least assist in producing the at least one baseband analog output signal; and a mixed signal feedback path operable to receive and process the at least one baseband analog output signal to produce the at least one digital feedback signal, and further operable to provide the at least one digital feedback signal to the DC offset correction circuit, wherein the transmit path correction system is operable to source the at least one baseband analog output signal for modulation by a modulator.
