Patent ID: 7342976

Claim:
A method of compensating for distortion introduced by analog-transmitter components of a digital communications transmitter, said method comprising: providing a digital-to-analog converter (D/A) and an analog-to-digital converter (A/D), said D/A eihibiting higher resolution than said A/D; digitizing, in said A/D, a first signal output by said D/A; in response to said first signal, compensating for distortion introduced by said A/D by processing an output of said A/D, said compensating activity including identifying switching thresholds used by said A/D and adjusting said switching thresholds to symmetrize guantization error; digitizing, in said A/D, a second signal output by analog-transmitter components; and in response to said second signal, counteracting distortion introduced by said analog-transmitter components by processing said output of said A/D.
