ABSTRACT:
A transmit path correction system (34) for compensating for digital DC offsets, I/Q gain imbalances and I/Q phase imbalances includes a mixed signal forward path (36) and a mixed signal feedback path (38). The forward pat (36), which is operable to process input data symbols to produce at least one analog output signal, preferably includes a digital DC offset correction circuit (86) for compensating for digital DC offsets in the forward path (36) using at least one digital feedback signal (82, 84), an I/Q phase equalization circuit (90) for compensating for the I/Q phase imbalances in the forward path (36), and an I/Q gain equalization circuit (88) for compensating for the I/Q gain imbalances in the forward path (36) using the digital feedback signal(s) (82, 84). The feedback pat (38) processes the analog output of the forward path (36) to produce the digital feedback signal(s) (82, 84).
